@Ughubughughughughughghlug a very interesting and nuanced post. Could you recommend any books?
People mention Rosa parks and are surprised that her action was planned - but I am pretty sure I was taught that at school. She was chosen because she was a respectable, neat looking lady of slightly older years. She would be very sympathetic. No one likes to see a respectable mum type manhandled, it’s bad optics. You can’t demonise them as a young Jezebel either.
I'm afraid not, most of my knowledge on this stuff comes from a bunch of little things I've read here and there and not a single source. Kuran's book was called Private Truths, Public Lies, he also talks about the caste system in India and support for Communism in the Soviet Union. A lot of it is common sense dolled up in economics, but his interesting insights are that very small things (like a single celebrity bucking the trend) can cause a snowball effect of public opinion, massive changes can happen overnight, and of course this idea that a population can be in a situation where everybody is unhappy, everybody knows everybody is unhappy, and the equilibrium still prevails because everyone's individual survival strategy relies on suppressing dissidents.
De Tocqueville talks in Democracy in America about Black hatred. Note that he otherwise strongly prefers New England culture (what a fag).
The Devil is Here in These Hills has parts where it talks about the Klan's use as a tool of business to suppress proletarian interests (and their failure). United States of Appalachia talks about Highlander Folk School.
The lynching actually comes from my own exploration of Historical Lynching Project data, the explanation was my own guesswork but it's common knowledge that blood feuds were common and Appalachia was the sort of lawless place that people imagine the West was.
Mistreatment of Mexicans comes from El Norte: The Forgotten History of Hispanic North America. There's other interesting things to say about Mexicans too, the earliest Texan settlers and Tejanos got on well together, it was only when the mass of Tennessean and other Southern volunteers flooded in that Texas went to shit and they became abusive. It got worse as time goes on. (Basically, Texas radicalized against Mexicans like the South did against Blacks, but for different reasons.)
I forgot something huge in my big post, there was a system of industrial slavery in the Jim Crow South. This one, I do know where I read it,
Slavery by Another Name. What they'd do is pass bullshit "vagrancy laws" where they made it illegal to do things like sit on your own porch without a pass, then arrest Blacks. English tradition was that sheriffs often were paid very little but could collect fines/fees for legal services, which obviously created perverse incentives for law enforcement to make unnecessary arrests. This was usually constrained by public sentiment (remember, sheriffs are elected officials), but in the Jim Crow South, they could get away with charging exorbitant fees to the "vagrants." Then, a White businessman, sometimes a farmer but often a manager for a coal mine, iron mine, steel mill, or turpentine plantation (turpentine is made from tree sap like rubber is) would pay the man's fee.
Whereas slaves were valuable property and so had a strong incentive to keep them in good health, these industrial slaves-but-we're-not-calling-them-slaves were relatively cheap and so would be fed into terrible conditions where they died. And unlike slavery, this system was easily extended to Whites as the bottom of the social pyramid too.
Teddy Roosevelt tried to crush it, but every time they'd just got stonewalled, like they did in the Mississippi Burning cases. It wasn't until FDR that they finally got that shit shut down. Slavery was actually perfectly legal as a legal punishment, so they went at it from the direction of debt peonage (same thing they used against the slavery of Indians/Mexicans in the Southwest).
It's also interesting, Mississippi actually had an (informal) state secret police dedicated to surveilling the Black population.
