I went to private school and for my parents to be able to write a big arse check for me to go every year is a privilege. It might not be rich.
While public schools give out breakfast so kids are not hungry is a huge difference in the social scale.
So yeah not rich but definitely comfortable if you can go to Jesuit.
I know other people who's parents had to take out loans so they could go to private school. Not rich but at least could finance it. They were not hungry either.
I would like to see her donate to something that helps all children. Considering the 5 million is like be giving 20 to a charity.
