"We sometimes, for example, hear it said," writes John Stuart Mill in his Principles of Political Economy, "that governments ought to confine themselves to affording protection against force and fraud"; that people should otherwise be "free agents, able to take care of themselves."

Much like Mill, Paul Krugman likes capitalism's innovations but not its crises and thinks that government has a duty to facilitate the former and protect us from the latter. He doubts that citizens will get much protection from moguls--or from most economists, for that matter--unless we trouble to grasp how the whole intricate game works, so that our legislators will form a consensus about how to regulate it.
