What would be the practical difference between a war between the races and a war between the haves and have nots?
The answer, of course, is nothing. The only issue here is that you see the former as a possibility and the latter as not possible.
I disagree with the idea that the latter is not possible, and that the former is even close to likely. And if I have to blame anyone (it seems that that’s important to you) I would blame the technocrats in both parties who have supported policies with funnel jobs and income away from our working class and into the wallets of the government and megacorporations.
Hope that helps.
