Good going USA. It's too bad Africa as a whole didn't manage the same. But you know, the people in the now USA who did the overthrowing were themselves Europeans. After all, the native Americans are not running things today are they?
It's harder to exploit people who have the institutional/cultural knowledge to fight back.
And still, lots of natives in colonies managed to overthrow their exploiters, usually with higher technology or more ressources than their original hunter-gatherer culture had.
Native Americans were outmatched by the population pressure from Europe. They didn't get the time to develop agriculture and everything to the point that they could compete in population density. And on top of that, a lot of violence, accidental harm and wrongful deeds have been done to them.
