Beto O'Rourke is patting himself on the back for admitting that his ancestors owned slaves. This is how it works though. The way wealth moves around in capitalism is that is actually doesn't move around that much at all save from generation to generation. A rich person today once stole the work of unfree people. A successful company today once benefitted from unfree labor. Wealth concentrates into fewer and fewer hands. Marx and the other thinkers who pointed this out were right. Show me a wealthy person, I'll show you someone who benefitted from exploitation, if not outright slavery.
