But there's one thing he does hint at, though he doesn't quite come out and say it: bigger banks might be better for regulators. It may not be smart to put all your eggs in one basket . . . but it's probably a hell of a lot easier for a regulator to watch that basket. Plus, big banks provide nice lots of cushy jobs for regulators to retire into. Small banks don't have quite the same incentives (or payrolls). This may explain something important about what's happened in our banking system over the last few decades.
