there's also the whole racism thing. north american settlers basically wanted nothing to do with the natives, except to claim their territory. we have a folktale of the one time a white guy and a native girl got together and it was "a big disaster". latin america has its own racism problems, but there was way more race mixing which is probably a more important diver of assimilation than who controls the power.
