To me it looks like we need a few very wealthy people who are actually NOT evil. Do these even exist?

That is the disadvantage of being cynical - even when the few good wealthy people want to help, you'll reject them as being fake, as being the enemy.

I prefer to believe in people.

As for good wealthy people - I used to be part of that world and yes, there are many. Many more than you can imagine.

What is almost impossible to find are good Corporate people. To get where they are corrupts them.
