We're rapidly moving to a world where the billionaires, and soon, trillionaires own EVERYTHING of value, and we're all simply forced to pay rent on it all. They want to turn the entire world into sharecroppers. You don't own the land, you don't own the tools, you don't own the factories, you don't own the transportation, you don't own the stores, you can't even buy and sell anything without paying rent to the banks or the marketplace. You just labor to enrich capitalists.
The entire notion of a middle class is disappearing. They don't want a middle class who could ultimately challenge their position at the top with class mobility. They just want a class of sycophants who are afforded somewhat higher pay before it is again extracted through rents.
