The question is why are we kept here. Why does nothing progress?
Poverty and ignorance are profitable.
The same question was asked about the war on drug and "why does nothing progress?"
The answer, the American economy is heavily reliant on the many branches of the narco business.
I'll start with one: abolish public sector unions that protect police and teachers from the abuse their members inflict on the public they are meant to serve. Oh, suddenly it goes quiet and the appetite for change will vanish and we'll be back hearing about "systemic racism". Intentional vagueness to avoid real change.
Hint for anyone who doesn't get it yet: if you are a politician who's political office and not inconsiderable wealth is built on a combination of angry-black votes and union contributions, you don't want that shit fixed!
You are correct that there is no real desire for change from the top. Not everyone at the bottom of the pile wants change. That said, we cannot use that to dismiss the arguments of those who want real change because they have been victim of a broken system. The danger lies in painting everyone with a broad brush.
