J.P. Morgan CEO Jamie Dimon was a happy patriot during the financial crisis. He was among the first bank chieftains to accept government money when the financial world seemed to be coming apart at the seams, for example. But Jamie Dimon, as Deal Journal has written about before, now has had it up to his eyeballs in government regulation and banker bashing (though there have been signs of Dimon’s détante with the White House.) His latest diatribe, delivered before, delivered at the U.S. Chamber of Commerce conference in Washington, took on mortgage and derivative regulation, too big to fail, capital rules and foreign regulators.
