So you think that the US should start a nuclear war, that will end virtually every life on Earth...because a great power has been successfully operating under an economic system, that you don't like??? They're one of the US' leading trading partners, btw.
For the record, China has gone from one of the poorest countries on Earth, to one of the most prosperous, under that economic system, that you probably don't even understand. There are plenty of communists around the world - who think that China ISN'T really communist, and hasn't been, for quite some time.
You're living in a country where the vast majority of people can't afford a $1000 dollar emergency. A country where the top 1% owns more than vast swathes of the rest of us... An economy based upon sharing and mutual benefit might actually be an improvement in our lives.
People often mistake "communism" with authoritarianism or totalitarianism - both of which can exist under any kind of economic system. The technocratic totalitarianism that people criticize China for exhibiting (in some ways), was actually built by US Corporations and Billionaires, like Peter Thiel (a friend of your dear leader Trump's). It's on its way here - but won't be coming with free medical care, education or guaranteed housing.
