Communism and capitalism are both archaic—ways to distribute scarcity.
But science and engineering have made scarcity unnecessary. We can have near limitless energy and more than enough food and shelter for every person on Earth. And amazing healthcare.
The old archaic systems protect themselves (and their elite masters) at the expense of the vast majority of people.
This must and will change. Scarcity and therefore control of unnecessary scarcity will collapse. As it should.
