Bernie and his supporters don't think it's evil just to be wealthy.

We get it that there are some decent people who have ended up with money. That there are some wealthy people who have some personally progressive values.

It isn't about demonizing everyone who happens to have done well for themselves.

The problem is the system itself, and the ideas that currently define that system:

The idea that high short-term rate-of-return for investors is the ONLY thing that matters...that matters more even than actually building a business or providing quality services or goods.

The idea that, in the name of that short-term rate-of-return, it doesn't matter who or what is sacrificed.

The idea that the decisions made that determine who and what gets sacrificed should be made by a few, in secret, on the spur of the moment, with no means of appealing them.

The idea that, in the end, nothing BUT profit for the few should matter.

There are some rich people who reject THOSE ideas.

Bernie, and his supporters, are willing to work with rich people like that.
