Nice video, but I'd like to elaborate on it a bit. I've studied these things rather extensively over the decades and can safely point out that the "most successful" communist countries are those that adopted the most capitalist and free market economies.
Communist China? They are communist in name only, but most of their economy - and the strongest parts - are essentially capitalist and free market. The country is essentially a thuggish dictatorship taking its sustenance from its capitalist and free market economy. In theoretical economic terms, there is very little "communist" about China, except for its totalitarian nature.
Great point, but "yes and no" about chinas communism. Yes the ECONOMY is
LARGELY capitalisitic in function, at the lower and mid levels,
-HOW SO EVER-
The CCP Chinese Communist Party control EVERYTHING at the "levers of power" meaning if you are in a medium or large business, your board is infiltrated, kickbacks and bribes are common and advancement or change of profession is very limited. So you can be running a great business, employing thousands of Chinese making good middle-class money (average pay is 25 cents AN HOUR.... so middle class money is like... I dunno, not much.)... and then just be disappeared.
So while low level nuts and bolts, very capitalist LOOKING.... at any time the CCP-belonging chief of police can come rape your daughter, the safe, burn the place down, and lets just say there will be no letter of reprimand in his file.... and of course, all of this is on a case by case basis so yes, "Thuggery" is basically the best description of how mid to high level "government" works in communism. The communist part is examplified in the lack of rule of law for anyone very high up in the ruling party.
