In the course of his excellent essay at In These Times on the folly of ocean-going utopias, SF author China Mieville describes libertarianism, that well-known opiate of the petit bourgeoisie and the wingnut bloggers:
Libertarianism …. is a theory of those who find it hard to avoid their taxes, who are too small, incompetent or insufficiently connected to win Iraq-reconstruction contracts, or otherwise chow at the state trough. In its maundering about a mythical ideal-type capitalism, libertarianism betrays its fear of actually existing capitalism, at which it cannot quite succeed. It is a philosophy of capitalist inadequacy.
Heh. Indeed.
