Come ridurre alla fame il calamaro-vampiro della finanza

BERKELEY – Il settore finanziario americano sta davvero succhiando il sangue alla sua economia reale? La descrizione memorabile della Goldman Sachs da parte del giornalista Matt Taibbi nel 2009 come “un gran calamaro-vampiro avviluppato alla faccia dell’umanità che succhia il sangue da qualsiasi cosa che odori di denaro” risuona ancora e con ragione.

Nel 2011 ho osservato che la finanza e le assicurazioni statunitensi rappresentavano nel 1950 il 2,8% del PIL rispetto all’8,4% del PIL registrato tre anni dopo la peggiore crisi finanziaria in circa ottant’ anni. “Se gli USA riuscissero ad ottenere un profitto dai 750 miliardi di dollari che vengono sottratti ai contributi di chi produce beni e fornisce servizi direttamente utili, ciò sarebbe evidente nelle statistiche.”

Al tempo avevo sostenuto che questo dirottamento consistente di risorse “dai beni e dai servizi direttamente utili è un buon affare solo se incoraggia la crescita economica annuale complessiva dello 0,3% (o del 6% ogni 25 anni)”.

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships.
