No shit. What do you expect from an entire "civilization" that was, and to a point still is today, based on intertribal warfare. Fuck, that's also how so many slaves were got in Africa. Greedy as tribal leaders capturing and selling prisoners to the jews for weapons and shiny things.
Mexico and the majority of Central and S. America ended slavery before the United States. What colonialist didn't bring slaves to America? All the Europeans that came over brought slaves.
