Una luce sulle città

NEW YORK – Lo scorso mese si è tenuto un importante meeting a Medellín, in Colombia. 22.000 persone si sono date appuntamento per partecipare al World Urban Forum e discutere sul futuro delle città. Il focus era creare “città per la vita”, ossia, promuovere uno sviluppo equo negli ambienti urbani in cui già vive la maggioranza dei cittadini del mondo, e in cui risiederanno due terzi della popolazione mondiale entro l’anno 2050.

Il luogo stesso scelto per il forum era simbolico: un tempo famoso per i trafficanti di droga, Medellín ora vanta una buona reputazione come una delle città più innovative al mondo. La storia della trasformazione di questa città può essere di insegnamento per le aree urbane di altre parti del mondo.

Negli anni 80 e 90, i boss del cartello come il famigerato Pablo Escobar controllavano le strade di Medellín e la sua politica. La fonte del potere di Escobar non era solo il commercio internazionale di cocaina altamente redditizio (e alimentato dalla domanda negli Stati Uniti), ma anche dall’estrema disuguaglianza di Medellín e della Colombia. Nelle Ande, sui ripidi pendii della valle che culla la città, vaste baraccopoli, praticamente abbandonate dal governo, fornivano una pronta offerta di reclute per i cartelli. In assenza di servizi pubblici, Escobar conquistava il cuore e la mente dei più poveri di Medellín con la sua generosità – anche se terrorizzava la città.

    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.
