Die große Einkommenskluft

WASHINGTON, DC – Thomas Pikettys Buch Das Kapital im 21. Jahrhundert stellte den Zusammenhang zwischen Kapitalakkumulation und Ungleichheit in den Mittelpunkt der ökonomischen Debatte und erregte weltweit Aufmerksamkeit. Was Pikettys Argumentation so besonders macht, ist sein Beharren auf einem grundlegenden Trend, der mit der Natur des kapitalistischen Wachstums eng verbunden ist. Diese Argumentation liegt ganz in der Tradition der großen Ökonomen des 19. und frühen 20. Jahrhunderts. Auch im Zeitalter der Tweets ist sein Bestseller kaum weniger als tausend Seiten dick.

Die Veröffentlichung des Buches folgt auf über ein Jahrzehnt gründlichster Recherche von Piketty und anderen, darunter Tony Atkinson von der Oxford University. Beim Umgang mit dem enormen Datenvolumen gab es kleine Probleme, insbesondere bei der Messung der Kapitaleinkünfte in Großbritannien. Aber die festgestellten langfristigen Trends – ein wachsender Einkommensanteil der Kapitaleigner und die Konzentration von „Primäreinkommen“ (vor Steuern und Abgaben) ganz oben in der Einkommenspyramide in den Vereinigten Staaten und anderen großen Volkswirtschaften – bleiben eindeutig.

Das Gesetz des abnehmenden Grenzertrags lässt erwarten, dass die Rendite jeder zusätzlichen Kapitaleinheit geringer wird. Ein Schlüssel zu Pikettys Ergebnissen liegt darin, dass in den letzten Jahrzehnten die Kapitalrendite, wenn überhaupt, proportional viel weniger abgenommen hat als die Wachstumsrate des Kapitals, was zu einem wachsenden Anteil von Kapitaleinkünften geführt hat.

    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.
