One Good Result of the Bernie Sanders Presidential Run....

...is that Paul Krugman, as a Hillary Clinton enforcer, has stepped away from a lot of his usual interventionist prop up the state arguments, to actually make sound arguments to attack Bernie Sanders. Today, for example, Krugman's column at NYT contains this:

From the beginning, many and probably most liberal policy wonks were skeptical about Bernie Sanders. On many major issues — including the signature issues of his campaign, especially financial reform — he seemed to go for easy slogans over hard thinking. And his political theory of change, his waving away of limits, seemed utterly unrealistic.

Some Sanders supporters responded angrily when these concerns were raised, immediately accusing anyone expressing doubts about their hero of being corrupt if not actually criminal. But intolerance and cultishness from some of a candidate’s supporters are one thing; what about the candidate himself?

Unfortunately, in the past few days the answer has become all too clear: Mr. Sanders is starting to sound like his worst followers. Bernie is becoming a Bernie Bro.

Let me illustrate the point about issues by talking about bank reform.

The easy slogan here is “Break up the big banks.” It’s obvious why this slogan is appealing from a political point of view: Wall Street supplies an excellent cast of villains. But were big banks really at the heart of the financial crisis, and would breaking them up protect us from future crises?

Many analysts concluded years ago that the answers to both questions were no. Predatory lending was largely carried out by smaller, non-Wall Street institutions like Countrywide Financial; the crisis itself was centered not on big banks but on “shadow banks” like Lehman Brothers that weren’t necessarily that big.

As far as it goes, not bad.
