Most education in this country is a democrat fascist brainwashing and recruiting machine that soaks up taxpayer money like a sponge in return for spewing anti-Christ, anti-American, anti-Freedom, propaganda.

The health care sector has been driven into horrible shape by a combination of government regulation and MBA driven "profit center" thinking and has been at the mercy of the government and government run programs for quite a while.
