Some debate!
The above is not what I'm thinking about at all.
Her conversation is about shielding other millionaires from the inherent 'problem' of wealth. There are things you can do with wealth to make yourself feel better.
It's not the 'wealth' that should be the problem but, here, it's her clear short sightedness that she uses as a spotlight and a shield. She talks to 11 other millionaires? What about finding happiness in wealth??
There are people with no clean water in Flint; do something, affect lives in practical ways, rather than workshops or whatever.
If, by her reasoning, her own brother resents her giving out 20K yearly, or whatever it was, she has a problem she can't identify, cos she doesn't want to.
