The idea that the American economy was centrally planned in 1967 or any time after that, is laughable. The government has made policies and enforced them, but no one is telling IBM how much R&D to allocate to chip research, except IBM's stake holders. And the reference that US corporations sometimes have budgets larger than country budgets is unimportant in the context of the overall US GDP. Apple's economy is dwarfed by the US's, and their ascendance to massive wealth proves the point that the US economy is built on the disruption of established markets.
I can think of no actual centrally planned economies that pay more than lip service to democracy, nor any that have compared favorably with free-er market economies in improving the lives of the average person. Humans tend towards corruption, and free markets are the best tool we have for managing that. Want to see brutal, selfish, horrifying corruption, just look at your local centrally planned economy where the greed represented by a McDonalds happy meal campaign is instead implemented by the local police force.
