I believe you will find that Marx meant something quite different by "capitalism" when he coined the word back in the mid 1900s. It is a nice little pejorative (like "neo-con") that you can hurl at your enemies, real or imagined.

We do indeed have a "mixed economy", a mixture of free market and government control, and it works well. Pure Socialism would destroy everything we have built.

Tomorrow, 2 NOV 2010 will be a referendum on Obama and his Socialist agenda. Expect an earthquake.
