this along to your conservative friends. Murray Rothbard, the great libertarian thinker and economist, blasted Reagan two decades ago and accurately predicted many of the problems we now face today as a result of similar policies by the Bush administration.
You're not going to convince many conservatives that Reagan was a tax-and-spend, big government politician by pointing them to Krugman's piece in the Times. After all, Krugman is the quintessential liberal in their eyes; however, criticism from Rothbard, the ultimate advocate of the free market who would never be confused with the left wing, might prove convincing for some.
