“Kindleberger saw this not as dumb policy error, but, according to his biographer, the economist Perry Mehrling, as central bankers being overwhelmed and without a leader among them to stand up and support the international monetary system to guarantee that cash and credit could keep moving.

In 1929, the British couldn’t and the United States wouldn’t.” The old world had died and the new hadn’t yet been born, to paraphrase another great economist.”
