lemmygrad, I love you, but this meme is not communist enough. The post title would be much better simply as:

The US has the world's highest incarceration rate at 6x the global average. The rate continues to rise each year due to lobbying from capitalists profiting from literal slave labor in private prisons

Why?

• 6x is bigger than 4x. More embarassing that way.
• Incarceration rate itself is something that many Americans are unconcerned with. You need to connect the bad thing with facts which are unflattering to the American ego, such as the widespread existence of private prisons which profit from forced labor and the rich politians who are rewarded for their continued complicity.
• Making a direct comparison to China invites whataboutist counterarguments from reactionaries. They could point to capitalist societies which both technically have lower incarceration rates than China, such as Japan or Norway.

I mean, are those the official numbers from China? Because you know, there certainly are no secret reeducation camps in China. None wharsoewer. That would be ridiculous.

True two months ago but now China has achieved something entirely impossible for the US, namely the imprisonment of more people than even live in the US: Nearly 400 million people are under covid lockdown in China
