IN A POST about the higher education bubble (which you should read), Instapundit dredged up this Heinlein quote about 'hippiedom' which I had forgotten:

Hippydom is not itself a culture (as the hippies seem to think) as it has no economic foundation; it can exist only as a parasitic excrescence to the ‘square’ culture.

That quote to me perfectly describes the current state of liberalism.
