People get into debt because they are unable to handle capital.
Employment is beneficial to keeping our society running.
Taking this economic system down now would cause so much loving chaos, and an even greedier starfish with a seemingly good economic system which turns out to be really stuffty would fill this vacuum of economic power. And yes, people need an economic system to keep order.
We are not enslaving anybody, any countries who are so called "enslaved" economically to the US just have stuffty governments that allow us to invest capital in businesses and regulate those businesses that they allowed us to setup up over there.
The only way this would work if is there was 1 person left on the earth with these ideals.
