Socialism, Communism, Mercantilism, and Capitalism?

(to use pension fund as an example)

Yes but isn’t that saying socialism if enhanced would therefore be not the little amount of your wage taken for a pension fund, but rather your whole wage is owned by somebody else and they tell you what to do with all of your money aka communism. So socialism is a smaller degree of communism whereas communism does what socialism does but on everything, not just a pension fund. And in communism you can keep your money but the only choices you have to spend your money, outside of the black market, are at publicly owned places.
