Paul Krugman:

I was startled last week when Mr. Obama, in an interview with Bloomberg News, questioned the case for limiting financial-sector pay: “Why is it,” he asked, “that we’re going to cap executive compensation for Wall Street bankers but not Silicon Valley entrepreneurs or N.F.L. football players?”

That’s an astonishing remark — and not just because the National Football League does, in fact, have pay caps. Tech firms don’t crash the whole world’s operating system when they go bankrupt; quarterbacks who make too many risky passes don’t have to be rescued with hundred-billion-dollar bailouts.
