Weigh More, Pay More

Mar 12, 2012 Peter Singer

Obesity is an ethical issue, because an increase in weight by some imposes costs on others. That is why obese people should be subject to transport surcharges, and why foods that make people fat should be subject to higher taxes.

MELBOURNE – We are getting fatter. In Australia, the United States, and many other countries, it has become commonplace to see people so fat that they waddle rather than walk. The rise in obesity is steepest in the developed world, but it is occurring in middle-income and poor countries as well.

Is a person’s weight his or her own business? Should we simply become more accepting of diverse body shapes? I don’t think so. Obesity is an ethical issue, because an increase in weight by some imposes costs on others.

I am writing this at an airport. A slight Asian woman has checked in with, I would guess, about 40 kilograms (88 pounds) of suitcases and boxes. She pays extra for exceeding the weight allowance. A man who must weigh at least 40 kilos more than she does, but whose baggage is under the limit, pays nothing. Yet, in terms of the airplane’s fuel consumption, it is all the same whether the extra weight is baggage or body fat.

I agrees with the article partly.Considered in societ's view ,obesity has been a really trouble,which needs to be solved.Just as the writter says, the large quantity of fat people adds the costs of the normal function of societ,and harms the environment.But ,if we consider the question in a person's view,I don't think fat people are not comparable to thin people，that's too arbitary . And if a person is willing to overeat,we can not condemn him ,because it is his rights. So I think we should try reducing the quantity of fat people ,but we can never discriminate against them.

Maybe we should not blame people for their obesity. The food we eat, some of which is produced by the factory can also be the reason. Maybe it is this world and time changes people instead of people themselves.

I agree with the author's idea that we should pay more, if we weigh more. However, auther's measures to reduce the extra cost of fuel caused by obesity might be unfair. We know that as people grow taller, their weight always increases. So we cannot just set only one standard. It might be better to set different standards according to their height.
Additionally, the reason of obesity varies from person to person. So we need to consider a combination of factors, and then we can take measures that vary from person to person to help them keep fit and protect environment. I believe it is going to be a long road to change the situation.

Although the increase of people overweight will indeed cause some trouble and extra costs, I still think a person's weight is his or her own business. Because weight, like height, is a property of human that vary from person to person and people should be given the freedom and right to determine their own appearance. Besides, there were many research having shown obesity may be determined by genes. Since we can't actually get to know is genes or bad living habits that cause one'fatness. Should we simply ask them to pay more for their obesity? I think we may advocate for a healthier living habit or taxing on junk food to control the increase and conserve source and energy. But we shouldn't simply ask them to pay more for their obesity.

We can not say if all of us become thinner the world will be better. If that, the fat is becoming our enemies not just for you, but for everybody.It likes that if you are fat and you don't want to lose weight or just can not lose weight, you will be our enemy, and many people will blame you with the moral reasons.

I don't think that the two solutions are practicable at least in our real lives. Maybe you can say that the ways are reasonable, and you can supply lots of data information to prove the validity of your own idea. However, most of the fat people would be unhappy , feeling it is unfair and even considering it as the discrimination. And the number of fat people who used to choose the plane will come down, which counts the loss of economy to some degree. Maybe you do solve the problem of fuel, but leads to the bigger social problem, which is beyond your imagination.

What is weight? It's one of the many human attributes that quite a few people on earth aren't able to totally control, for they have congenital differences( maybe genetically) or their lives are occupied by working without a healthy lifestyle only to make a living. If weight is quantified and strictly discriminated, what about height, width, race and other properties that are meant to be treated equally?
I mean, instead of wasting our time on seperating the whole human race by these so-called standards, why don't we make a move towards one of the underlying problems—— the gap between the rich and the poor? Yes, I agree with the saying of "Weigh More, Pay More", with the finacial meaning of "weight" being focused on.

Passengers have different shapes and sizes, and so do their health conditions. If you focus on the obesity, then you shouldn’t only use “weight” as a standard to limit people who are healthy, strong, but their weight is over the standard and charge them for adding the load of vehicles. We need people to be healthy, but not to be slim to avoid the extra fee. Also, the increasing mass from people only takes a little part of the mass of the plane itself and there is no reason for charging people differently – big size people are not provided with seats suitable for them as well. The important thing we should think about is that we need to change facilities more than charge people. Seats need to be improved to make passengers more comfortable, engines should be more effectively and efficiently, clean fuel should replace original one, etc.

It’s a good imagine to charge more for fats to get people be careful with there health and protect our environment, but the inescapable fact is that some people are obesity because of their genes. Is it reasonable to ask them to pay more for their natural defects? How do we determine why someone is obese? Are overweight people necessarily bad for the environment and human society? There are too many questions waiting to be answer.

The article demonstrates the drawbacks of being obese. From a interesting view of analyzing the effect on transportation. From the point of “Weigh more, Pay more” to explain how obesity does harm to ourselves or even the society. This article introduced to us some different rules of taking planes depending on weights. It sounds ridiculous while I think companies of this sort cannot judge people from their weight. However, when I read the reason of ruling like this, I found it made sense actually. About resource, more weight indeed need more fuels and more room, which add to the total cost. Therefore, the decision of making differences by their weight can be a effective way to some degree. Thus, we need to be slim buy strong, thin but healthy. Not being obese, good for ourselves while good for the whole community as well!

Obesity truly brings financial burden, but the author’s assumption that removing obesity is too ideal. Obesity always comes up with a growing economy.

His idea of taking more money from heavier people may sound reasonable, but it is too hard to practice, and possibly raise prejudice issues, which are far more difficult to tackle. Rise the airline fare by a little may be a more simple yet effective method.

obesity is a serious problem, but the author focused on the extra cost in airlines caused by obesity. I don’t think that is a big trouble.

Compared to an essay, I think this article is more like a speech draft. It indicates the seriousness of extremely obesity emotionally, but the arguements lack accuracy in fact and logic.

Males and females have totally different body structures. You cannot ask a 180 cm tall man to have the same weight with a 160cm short woman. So this is not a convincing example.

Late to the conversation, but this was just on my facebook feed. One of the problems that I see as someone that works in healthcare is just weight used as a measure is a fallacy. For example I am six foot four, should I be charged more due to genetics? After all not only do we weigh more, but we are also taller on average taller. Why isn't this issue addressed? So, we could go with BMI, but that too is imperfect, because a body builder has a high BMI as does an obese person. Maybe the airlines should have everyone weigh in regardless and charge per ounce or kilo. I could see some discount carriers doing this.

  @ Rick Lundgren:
  No one said anything about height. Your height is irrelevant to this article. To a plane, all that matters is the load/weight. If you want more space, buy a business or first class ticket.
  Also Peter's point was that airlines should weigh the passengers with their luggage, and therefore obese passengers would have to pay more, not single out all the obese passengers and make them pay more full stop.
  By the way, "Should you be charged more due to your genetics?" People with genetic predisposition to something and are aware, would take active appropriate actions. If they are more prone to say lung cancer, then they would or should actively choose to not smoke. This statement is twisting the original argument as it is weight not height that is at stake here. Also even if your genetically predisposed to gaining more weight, then you would actively choose to do more exercise.

  Not sure if you, Peter Singer, will see this but if you do I'd like to say thank you for posting this, my thoughts exactly on all issues. Thank you for coming out and writing this article.
  -It is not good enough for anyone to say "I can't help being obese/a smoker/a drug addict/an abuser." You should make a conscious decision to stop, even if it means to get help. Would it be okay if I said "I cannot help being violent, I am just addicted to bashing people up." No. If I knew it was wrong I'd go get help from anger management. Same thing.
  -I am that slight Asian woman (figuritively speaking) with overweight bags and have to pay excess fees, when my co-passenger doesn't have to even though he himself weighs more than my luggage and me. In fact I am not even 40kg. Not fair, because ultimately airlines provide a service, their service is to carry a load, and there is only so much load it can carry, and will not and should not discriminate where the load comes from. Each ticket/seat should be allocated a certain weight and that is your combined weight. Go over pay more, simple. That way people travelling together can even share the load, because at the end of the day, a 40 kg person won't be able to carry 100kg worth of luggage anyway.

obesity is a social-public disease, not a private one. it's also a disease of poverty in the rich countries. There is just often very little option but to eat unhealthy or very expensive. Not only in restaurants, but also in supermarkets, junk food is much cheaper and much easier. And finally, having the time to cook healthy food is also a cost many can't afford in the current world (think as an economist: aggregate labor demand for different type of jobs, price of good food, ect..)

I agree with other posts on the following: up to which point are we going to "discriminate" individuals in order to have everyone paying his own price?
This would mean measuring with no end everyone's behaviour, genes and preferences to determine it's price - and I don't think rationalising ad infinitum humans is worth doing, doable and liveable.
It is not doable, but a few behaviours/features are picked to be segregated. It would be interesting to analyse why it's always to fat and the smokers who are to be blamed (despite the very minimal cost brought - come on: what's 25 Kg on a A380?) compared to other behaviours (prevention of accident within the house, driving attitude, walking attitude ?
Is it because it's easy to measure. Or is there a bit of a religion - call it "Hygenism"- in that? Both probably.

An aside: If the issue were primarily one of metabolism, that'd be some might fast evolution we are experiencing. But somehow I doubt obesity bestows an advantage in propagating one's genes. Methinks the sad but hard truth is diet and lifestyle. To the credit of the, um, bulk of the obese, 14 hour work days garnished with fast food do seem part of an inescapable fate for many.

First, stop writing at airports. Nothing publishable can come of writing in such conditions.

Second, stop pretending you are an economist. You are an admirable extremist, who by taking certain propositions to their logical extreme conclusion have managed to say some important things in moral philosophy. But you have absolutely no training in the logistical consequentialist methods of economics and so you can say nothing sensible about 'true prices'.

Third, your moral distinctions here are invidious or incoherent. Either this is a general principle which applies equally to the disabled and pregnant, in which case it is invidious. Or you are in fact punishing obese people for their sin, in which case you are incoherent. On this note my first point. Stop writing in airports.
- MK Anon Sep 10, 2012
  
  Thanks for pointing this out. Ailrline's prices are really not related to costs like that, but rather "market discrimination". Does it cost more to operate a place if you buy your tickets 3 days for rather than 6 months? nope. the 15k thousands premium for first class is unrelated with space and luggage load, its rather a positioning good. Companies actually try to have an offer that fit the most closely the willingness to pay of consumers to maximise profit.

You refer to obesity and ill-health due to excess fat. But then seamlessly talk of surcharging people above 75Kg as if that represents an unhealthy weight. Let's look at the data.

Someone weighing 75Kg would only need to be 175cm tall (5'8") for their BMI to be below 25, putting them in the normal, healthy range - not even overweight. To be classed as obese (BMI over 30) at 75Kg you would need to be under 158cm (5'2").

Comparing those heights to a chart of caucasian male heights, even the 5th centile for an adult man is around 168cm. Median is about 178cm. Hence, we can conclude that for the vast majority of men, 75Kg would not be considered obese and for most men it would not even be overweight (BMI over 25).

Even for women, 158cm lies somewhere between the 5th and 25th centiles so again most women would not be obese at 75kg.

Your proposal also raises an interesting question about equality: someone's height is quite strongly correlated with their sex and their race, thus the impact of your charge would fall disproportionately on men and on taller races.

Richer nations are more likely to use airlines, and among those populations you tend to find that poor people are more likely to be obese. So you're also likely to be proposing a surcharge on being poor or a subsidy on being well off.

In short, any analysis of the impact of your plan is likely to conclude that it's sexist, racist and anti-poor.

Ultimately a person's mass is a fairly insignificant portion of the overall mass being moved - around 0.01% in the A380 example given – and there’s no reason that people of differing weights should be charged differently for use of the plane’s aerodynamic capabilities. More thoughts on that here:

How about a surcharge for people who are so excessively rational and non-empathetic that they create arguments against treating other humans as equals? It seems like they ought to bear the true costs of their antisocial behavior!

Fred Seamons Mar 14, 2012

Yea, and while we're at it we should think about charging for cell phones, internet etc only on the specific amount of letters, words, or usage. And, don't forget we could be charging for gas by the amount of emmisions.your particular car puts out. And, a surcharge on the amount of garbage each individual generates, including when we are eating out etc. And, we chould be charging teachers a surcharge for the amount of paper they generate. It appears that there is no end to the surcharges we should be charging for all the extra costs that are generated by those who are using above the average or accepted level. And maybe we should be able to vote on the so called excess people on the planet that we could do without, so the amount of environmental damage could be held to an agreed upon level.

Passengers come in all shapes and sizes; seats don't. Current seats are made for someone less than 5'9" and 170 lbs. Airlines need to make seats larger and provide more legroom for all passengers. (They used to.)

This is not a luxury, as the tight seating in coach has been implicated in many passenger deaths from blood clots. Being small, thin, or fit does not help if you can't move because the seat is too small.

Should the airlines charge more for larger seats and more leg room? Of course, but a less tightly packed plane will make all passengers happier.

Charging more for heavy passengers but not providing adequate seating for all does not make any sense. In the example of charging the "overweight" passenger $ 29.00 more, will the seat be any larger? Will their be any extra legroom? Or just an extra fee to help the airline's bottom line?

BTW professor, flying is a right, at least here in the United States:
49 USC § 40103 - (2) "A citizen of the United States has a public right of transit through the navigable airspace.”

We don't need more and more fees-we need seats and legroom sized for today's travelers, not children. We don't need more taxes. And we don't need more wannabe dictators trying to decide how much everyone else should weigh and what they should, and should not eat.

Boeing typically states aircraft seating capacity, structural payload, and maximum takeoff weight (MTOW) for an average passenger plus luggage weight of 210 pounds (about 95 kilos).

If I weighed 75 kilos, I would be allowed luggage of 20 kilos before I was taxed for excess weight. If I weighed in at 90 kilos, just 5 kilos. If this was a hard rule, I think airlines already use it loosely, people pay for the excesses they want to ship beyond the capability for which the aircraft was designed. Of course, those seated in the front-end first class section have higher per weight figures than the rear-end just on interior installations and the space these installations take-up.

Effectively, this discussion is at best a part of the broader debate with how to get people to live healthier lives, lessen the impact of medical costs on the squeezed budgets of many advanced nations. In short this debate is here to stay, and will feature more prominently in those advanced countries.

Lukas - Mar 12, 2012

This argument has a flaw. It says the point of the surcharge is “not to punish a sin”, but to reflect the “true cost of flying” So, it doesn’t matter if an obese person is responsible for her/his overweight or not.
According to this logic, it must then also be morally right to charge disabled people a higher ticket price, no matter if their need for a wheelchair etc. is their fault or not, since they also impose additional costs on their fellow passengers and their ticket price currently doesn't reflect their “true cost of flying”.

I think, the proposed surcharge is only justified for obese persons who freely choose to be overweight. There is no rationale for surcharging people whose obesity is caused by reasons they are not responsible for (e.g. a disease). Of course, those 2 groups cannot be distinguished in practice.

BTW, what about very tall people? They also weigh a lot. Will they also be charged more and if so, how is being tall different from being in a wheelchair (both conditions are not chosen)?
Furthermore, it's highly debatable whether flying is a human right or not. There exists the right for freedom of movement (UDHR Article 13) including cross-border movement, which often can only be done by flying.
