The country was founded by slave owners. After that we had various “industry barons” like railroads, petroleum, automobiles, etc. Now we have multinational corporations (with larger budgets and more power than several countries) calling the shots in congress. It’s always been like this. Post-WWII provided a brief respite, but that limited run of the “American Dream” was temporary and no longer exists.
Part of the solution would be: worker cooperatives. We need a lot more of those. It won’t solve everything, but it’s a really good start.
