The crisis in America that we barely notice anymore is that we've become two nations - divided by poverty, opportunity, and race. It's like a neighbor's car alarm that we don't hear anymore because it rings so often.

Market forces have no intrinsically moral direction, which is why, before he wrote The Wealth of Nations, Adam Smith wrote The Theory of Moral Sentiments. Ethics should precede economics. But it doesn't have to. . . .
