The mindset has shifted from "let non-whites become educated too" back during segregation, to "yeah fuck education we don't need that white shit anyway." Rather than encourage upward mobility, to elevate the disadvantaged, the idea instead is to bring everybody down to the lowest common denominator. This mindset has infiltrated everything, whether it's the public education system, or women's rights, etc. It's like when Margaret Thatcher said that these kinds of people (e.g. Bernie supporters now) would rather have the poor become poorer, provided the rich become less rich.
