PAUL KRUGMAN: To those defending Obama on the grounds that he’s saying what he has to politically, I have two answers. First, words matter — as people who rallied around Obama in the first place because of his eloquence should know. Yes, he has to make compromises on policy grounds — but that doesn’t mean he has to adopt the right’s rhetoric and arguments. The effect of his intellectual capitulation is that we now have only one side in the national argument. Second, since Obama keeps talking nonsense about economics, at what point do we stop giving him credit for actually knowing better? Maybe at some point we have to accept that he believes what he’s saying. The question then is why. As I’ve tried to show many times, the facts overwhelmingly refute the anti-Keynes talking points. Neither the invisible bond vigilantes nor the confidence fairy have made an appearance. So why is Obama talking up those talking points? OK, here’s an unprofessional speculation: maybe it’s personal. Maybe the president just doesn’t like the kind of people who tell him counterintuitive things, who say that the government is not like a family, that it’s not right for the government to tighten its belt when Americans are tightening theirs, that unemployment is not caused by lack of the right skills. Certainly just about all the people who might have tried to make that argument have left the administration or are leaving soon. And what’s left, I’m afraid, are the Very Serious People. It looks as if those are the people the president feels comfortable with. And that, of course, is a tragedy. Update: To commenters saying that I need to have dinner with the president, or vice versa — been there, done that, didn’t help. MORE
