And it apparently goes back from our civil war to the English one. The earliest English settlers on the east coast of the US left before the English civil war. So rather than settling matters there, they brought them here and fought another war about them.
We're still fighting that war. And as you point out, the war is class, it's not race, nor is it gender, religion, or political viewpoint. It's class, and the power and money required to hold onto privilege. That's what drives our society, and as far as I can tell every society.
That was sucks to be right these days.
