> apart from Black and Native American people

That's a pretty wide exception, and it's worth addressing why they remain an exception. Why are these groups so slow to economically integrate?

The simplest (and therefore most Occam's-razor-friendly) explanation for the black population is that they can't usually pass as "white" as easily as other demographics. But this doesn't really explain much for Native Americans, who could pass as "white" about as easily as Latinos and/or Asians.
