I have no doubt there are some in the US would do this IF possible.
Of course you're right.
We have psychopaths in our country too... it's just that we try to put psychopaths in our prisons not in our State Houses. The Chinese fill their 'leadership' posts with them.
And yes, we've seen some of that evil here... what with James Comey and other deep state thugs setting themselves up as more important than freely elected representatives of the people. AND do you know what we do? We fight them. When we see a psychopath in our government we fight them for years... and work to get them out of office. The hatred for Bill and Hillary Clinton will last for decades after they're both dead and buried.
What does China do when they discover psychopaths are leading their country? The brave few die objecting to them and the rest of the Chinese hand their heads low and buy road kill at wet markets - thankful they're not being murdered or tortured.
Chinese people do fine in free culture but they don't know how to create or hold a free culture and we don't have the room to add a billion people to the United States. Xi seems like a good man - chosen for that reason by the thugs who run China. It's all stupid and sad.
