Works how, to have them muzzled, jailed, and murdered? Russia and China are great examples of how communism stifles innovation. Other than defense products the Russians produced nothing of quality. Cars, machinery, planes, engines, health care, you name it...nothing but the poorest of quality. Education was the only area of strength, yet they failed in the long run at that too because of the environment that results from communism...a lack of competition. China's the same, they only began to become mroe productive as they moved towards capitalism. Communism is a failed experiment.
