It's more of a bell curve, on one side you have a totally controlled markets which makes people nothing more than slaves to their government, like it was in the USSR or in North Korea. Things like owning a small business or trading on currency markets, or flipping commodities were considered a crime punishable by prison or work camp. Even unemployment was illegal.

But totally free market with zero government intervention aren't good either, this can easily lead to monopolies, poor work workplace standards and lower salaries, no benefits for workers, lower quality goods. People will be theoretically free to do anything they want, but on practice they'll have no choice but to work under horrible conditions and have very little spare time.
