AK(47)[thanks for the nickname lol], even prior to the Obama administration, I don't think America could qualify as capitalist. Free compulsory education for the masses, subsidized higher level education for mostly everybody, social security, welfare, subsidies, heavy market regulations, public housing, zoning laws, regulated monopolies (1930s power industry vs. today, for instance). All of these are "socialist" policies that are deeply ingrained into our current economic structure.
It seems to me that we are a capitalist society which has been repeatedly willing to trade away the purity of its capitalism for peace of mind and a sense of self-righteousness.
