FWIW, you're nearly doubling the actual prison incarceration rate. There were about 1.25 million people in prison as of the most recent federal data (which covers up until 2023). 2MM is the number of people who were ever in a prison or jail in 2023 (including e.g. holding cells for drunk drivers), but there wasn't a point in which 2MM were in prison at a single point in time.
Nonetheless, America has >10x the number of murders per capita than China, so it's no surprise that it has nearly 10x the people in prison for murder per capita than China (in fact, it's surprising it's not >10x, to match the murder rate). Ditto for basically any crime rate you can think of.
The downside of America's system includes much higher crime rates, which ends up in higher incarceration rates. That doesn't discount that in America, much more is legal than in China: people in America commit a lot more crime, but also do a lot more things that are legal in America but illegal in China (e.g. mass rallies to protest the government). In the security/liberty tradeoff, America and China are pretty much opposite ends of the spectrum. There are downsides to both, and upsides; China is a much safer place than America.
Ah yes, nothing screams valuing personal freedom like having 2 million people *in prison* right now in US. A rate of what, one every 140 adults?
And nothing screams personal freedom like spying every single of it's citizens or hacking every single chip on this planet.
Hell, US respects your freedom so much, you can't even renounce their citizenship!!
