At his request, here is Daniel Klein proposing drug approval denationalization as a simple step toward a better world. I like the argument: basically, he argues that we should allow the international marketplace for drugs to be more competitive by getting the government to quit stopping drugs at the border. If something is approved for use in Canada, for example, there is no reason why Americans shouldn't be allowed to use it. That said, here's Dan:
The statesman who should attempt to direct private people in what manner they ought to employ their capitals would not only load himself with a most unnecessary attention, but assume an authority which could safely be trusted, not only to no single person, but to no council or senate whatever, and which would nowhere be so dangerous as in the hands of a man who had folly and presumption enough to fancy himself fit to exercise it. -Adam Smith
