The labor market is not a "free" market. The population is basically fixed, everyone could be employed and there could still be companies that want to hire at the market rate.

The whole purpose of markets is to try to satisfy our infinite wants with our finite means. That doesn't argue against a free market.

Still doesn't argue against it being a free market. There is no limit to how much we want to buy.
