>>511342095 (OP)Most slaves were mentally broken (learned helplessness, as shrinks would all it), and in the few cases where they were not, there were slave rebellions and dead slave owners. Those were quickly defeated every time, though, which elad to surviving slaves being even less willing to rise up.
If you read contemporary reports (summed up in kurt saxons "root rot", for example - that old nazi certainly didn't favor blacks in his selection of sources), there's plenty of stories of african slaves being tortured so badly by other africans that they just blindly did whatever they were told to do, up to the point of letting themselves be killed with no resistance.
Add to that that (most) white slave owners, while not exactly friendly, did not kill or cripple slaves for no reason (don't want to damage your tools, after all), and plantations might well have seemed like paradise to first-generation slaves.
Where it gets more interesting is rubber plantations, where indios were enslaved. Those people didn't have a culture of slavery, yet still, the vast majority of them was controlled by only a handful of whites within a few years. Mostly by divide and conquer, allying with one tribe for a while, then subduing them after their former enemies were already brought under control.
