Not only are you massively overgeneralizing, you're plain wrong. There's numerous examples of successful communes, the idea that they always end in failure is a myth. There's also lots of agrarian societies that are too primitive to even classify as capitalistic, that rely on barter and lack the formal institutions to allow for the consolidation of capital.

The naivete is also laughable. No, people do not have good houses, or any houses for that matter. Many people are forced into debt to own cars, because without one they can't maintain employment. One in eight families in America experience food insecurity, which is a pretty far cry from having lots of food.

Grow up and step outside of your bubble, your response reads like something written by a child.
