Has Paul Krugman's cheese finally slipped completely off his cracker?

Many believe Liberalism is a Mental Disorder. Paul Krugman is now advocating for a fake alien invasion to force more government spending on liberal projects.

PAUL KRUGMAN, NEW YORK TIMES: This is hard to get people to do, much better, obviously, to build bridges and roads and healthcare clinics and schools. But my proposed, I actually have a serious proposal which is that we have to get a bunch of scientists to tell us that we’re facing a threatened alien invasion, and in order to be prepared for that alien invasion we have to do things like build high-speed rail. And the, once we’ve recovered, we can say, “Look, there were no aliens.”

But look, I mean, whatever it takes because right now we need somebody to spend, and that somebody has to be the U.S. government.
