Yep there are a couple thousand people with an outsized impact on society and at anytime they could organize and do a lot of good. But they all sit by quietly and actively destroy the society that gave them so much.

That's not true! No matter what kind of billionaire he was in life, now he is a good billionaire. You might also say that all dead billionaires are good billionaires.

They still had family and friends, and people who loved them.

I agree that having such vast amounts of money can't be a good thing whichever way you look at it, but expressing joy when someone dies is just not civilized in my opinion. It just isn't.
