We don't, actually.

No it's not, it's just hidden so liberals (including republicans) don't have to think about it. It's the prison industrial complex.

Anything you read in the western media about China or North Korea should be second-guessed and double-checked against eastern media, usually chinese language, for facts. The so-called "free press" is really a coordinated operation run by a few media companies in the interests of the capitalist class. People supposedly iced by Kim Jong Un have been magically resurrected many times. Western media tries to put all the blame of the coronavirus deaths in the US on China "not coming forward" when they had months and months to prepare. The US has entire media structures like "Radio Free Asia" to spread anti-China propaganda.
