"Paul Krugman, a Nobel laureate Keynesian economist, is apparently so frustrated by the lack of support for an even larger second stimulus that he’s now saying on national television that an alien invasion of the U.S. might be just the thing to give the economy the boost it needs. On Sunday, Krugman appeared on CNN. Speaking with Harvard economist Ken Rogoff, he gave the same economic advice that he has been giving for years--that more government spending would cause the economy to rebound. Krugman quipped, “If we discovered that, you know, space aliens were planning to attack and we needed a massive buildup to counter the space alien threat and really inflation and budget deficits took secondary place to that, this slump would be over in 18 months,” he said. “And then if we discovered, oops, we made a mistake, there aren’t any aliens, we’d be better--” “We need Orson Welles, is what you’re saying,” Rogoff interrupted. “There was a ‘Twilight Zone’ episode like this in which scientists fake an alien threat in order to achieve world peace,” Krugman said. “Well, this time, we don’t need it, we need it in order to get some fiscal stimulus.” Krugman, like most liberal economists, believe that the economy improved while massive amounts of money was spent during the Depression and with the buildup of national defense during World War 2.
