Race has become less important than mindset- which is determined by beliefs and shared interests, both social and religious. Income is a factor in determining interests. But I can't deny that it isn't an important force in much of the world.

In this case, I think legislation exacerbates the problem.

Home schooling, allowed here in Alberta, and also growing in the States at the expense of the public system, is leading some kids into very peculiar beliefs indeed. Nothing wrong with the old tutor system, if the material covered in broad, but some parents ideas of education outside of the basic 3-R's is limited to their own very narrow mindset.
