If Mitt Romney is elected president, the U.S. will experience an economic disaster the likes of which have been recently seen in Ireland, according to Paul Krugman.

"Ireland is Romney economics in practice," the Nobel-Prize winning economist and New York Times columnist said on the Colbert Report on Monday. "I think Ireland is America's future if Romney is president." (h/t Politico.)

"They've laid off a large fraction of their public workforce, they've slashed spending, they've had extreme austerity programs, they haven't really raised taxes on corporations or the rich at all, they have 14 percent unemployment, 30 percent youth unemployment, zero economic growth," Krugman said.
