Yes - and yet there is still a range of educational outcomes, from excellent to abysmal. The country has a more generous welfare regime than when I was growing up, but AFAIK this hasn't substantially altered the educational landscape.

So your argument that poor educational outcomes can be attributed to inverted racism doesn't stand up. It may well be a factor, but you appear to be arguing that poor non-white kids with a bad attitude are primarily responsible for dragging down overall results, and I don't agree.
