There’s a pattern to this: First, there’s a crash; then comes a period of remorse and talk of reform; and eventually comes the great forgetting. As time passes, markets rise, greed becomes good, and Wall Street begins to champion more deregulation. The government attracts deregulatory enthusiasts and then, of course, there’s another crash, millions suffer, and remorse returns. Ominously, we’re now in the deregulation stage following the bull run. We know what comes next, just not when. Count on one thing: It won’t be pretty.
