“It didn’t work out (they died or ran off), so blacks were brought in to do the work.”
Tommy Sotomayor is a black guy with a youtube channel who claims you cant force someone to be a slave if they are non compliant. You can kill them or torture them but they can always run off, or rebel, making it a lot more trouble than its worth. Considering the small number of rebellions over the hundreds of years of slavery, I think his point was that blacks were compliant and that’s why they were good slaves. Whether that is true or not I dont know.
I thought it was primarily climate (rather than disposition) that made them desirable; there were always runaways, and scattered uprisings. Besides the more widely-known Nat Turner and Haitian revolts, the Danish West Indies (which eventually became the US Virgin Islands) had a bad one, and there was the Denmark Vesey plot in the Carolinas. As time went on and the slaves eventually were native-born, I’d imagine the desire to revolt probably declined as they’d known no other life (or place). Escape was desirable, but the idea of sailing elsewhere must have faded.
