Nobody said being wealthy is wrong. It was stated the system is unethical that allows one to die on the street with nothing, and another to possess all, where enough is available for everybody.
We don't have to take food from somebody's mouth to prevent them from eating. In an economic system where you must have dollars to find food, you need only prevent them from getting enough money. And I'm not even saying Jeff Bezos does this. Nobody does it on purpose. It occurs naturally is our economic system, so we must determine whether it is ethical.

it's also not a vacuum. The value of the dollars is nothing without a whole lot of other stuff going on. for instance: a 500B/yr standing military to protect the interests that keep those dollars valuable; a labor force that has been turned into a business commodity; the destruction of finite natural resources; the manipulation of the sovereignty of foreign peoples... it goes on.
