That doesn't seem to be true at all: Wikipedia says there was around 4 million slaves in the 1860 census while the total number of incarcerated Americans in 2010 doesnt reach 2.5 millions.
I didn't say total slaves vs. total prisoners - I said black men. https://www.huffingtonpost.com/2011/10/12/michelle-alexander... edit: I can't imagine why I'm being downvoted here. My statement was utterly correct, and when challenged I cited a credible source. What'd I do wrong?!
I've had enough experience doing volunteer work with people trying to complete their GED in/after prison that - despite the fact that I despise ultra-left fresh-out-of-college political babble (it's so disconnected from reality and non-constructive that it's reasonable to squash it with the rest of the noise) - I do believe that there are deep structural injustices in American society, and we really don't have a coherent story for how to fix them.
That shift in attitude was born of experience that is not universally shared, though. Most people have their hobbies and their jobs and their families and their insecurities and their resentments, and they don't take kindly to strangers telling them that the American social structure that passively benefits them and makes their lifestyle possible is built in part on some very deep nastiness.
Which isn't to point fingers, or level blame, or shame anyone. Those are the rhetorical techniques of demagogues, and they have neither truth value nor do they tend to point society in a better direction. It's just to say that the psychological landscape is complicated.
