The problem is substantially more complex than just the race issue. It starts with this country's long term denigration approach to blue collar work, lack of vocational training in k-12 like every other modern country in the world, a continued, on going insistence that everyone should get a university degree, entitlement to said degree, and the move to a profit driven university model.
I went to a minority high school in the 80s and the top kids got major scholarships to universities. With the mass demand of college bound kids, increasing costs, racial issues, entitlement, zero support by any political side of a vocational track in our early educational system and lack of funding relative to the increased demand and rising cost, you're bound to see a lot more vitriol, and we have.
It, like all major issues, is never a simplistic single item causality, and to try and make it one is a huge issue in our world today. Complex issues are complex, the cause and solutions are never 1 thing, but by god, we try to make it about 1 thing because its easier than actual discussion of the nuance and particulars.
