Desenvolvimento sustentável fácil e óbvio

BUDAPESTE – Os Objectivos de Desenvolvimento Sustentável (ODS) das Nações Unidas incluem nas suas metas o ensino básico para todas as crianças, empregos para todos os adultos e a erradicação da fome e da pobreza. Estas aspirações são nobres, mas os custos envolvidos são muito elevados. Teremos verdadeiramente capacidade para suportar tais custos?

A OCDE estimou que a concretização dos 17 ODS, que incluem 169 objectivos de desenvolvimento específicos, custaria anualmente entre 3,3 e 4,5 biliões de dólares — um montante praticamente equivalente ao orçamento federal dos EUA para 2016, e muito superior aos cerca de 132 mil milhões de dólares que foram gastos no ano passado a nível mundial em auxílio externo ao desenvolvimento.

Na verdade, só o ensino básico universal exigiria, pelo menos, 17 mil milhões de dólares de despesas adicionais por ano, e um comité intergovernamental da Assembleia Geral da ONU estima que para erradicar a pobreza seriam necessários investimentos anuais em infra-estruturas num montante entre 5 e 7 mil milhões de dólares a nível mundial. Na verdade, as estimativas variam porque ninguém sabe exactamente quanto custarão os ODS.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
