There are theories in psychology and there are experiments. You could read these papers and perform the experiments can come to the same conclusions (if they were reasonable to begin with and not biased). Politics and social structures evolve in strategy but are essentially similar (you can read old newspaper articles and while the language is no longer appropriate, you see the same arguments rehashed today with different window dressing). These are forms of economic control by the wealthy and essentially appeal to racism and classism. We had slavery, then redlining, and then a war on drugs. And now we have failed cities. This structure has been maintained throughout society since America was founded and is passed along generation lines. You do see a dampening effect between generations unless some conflict reinforces it (largely economic/resource competition). But a conflict can be unifying as well. For example WWII had a unifying effect since a GI was a GI. But if we had diverse neighborhoods, schools and work opportunities we would rapidly see a more humane world.
