"communist" countries are simply countries that are still operating within Global Capitalism that happen to be run by parties that are made up of communists. They would also freely admit that. There are no communist countries because communism isn't here yet.
Free markets, on the other hand, work even if they aren't perfect. The more free they are, the better they work.
