I assume this is a lighthearted joke, but in all seriousness I think part of where we go wrong as a culture is fantasies of good billionaires, than instead of constraining the almost limitless power money gives people we imagine people like us having access to that power and all the good we could do with it. When in really 95% of the time the sort of personality you need to acquire that sort of money means you're not going to spend it compassionately

and in the remaining 5% of cases, like JK Rowling who did actually get rich by creating something people enjoyed at least rather than exploding Amazon warehouse workers or manipulating social media users or whatever, just having that much money isolates people so much from the everyday lives of normal humans that they do seem to drift away from caring about making things better and in her case actively use it to make things worse

Probably best to leave Mouldemort out of it, considering she financed this abomination of a case. That her books were enjoyed by millions is undeniable, but their quality or originality absolutely is not.
Whether that was intended as a joke or not, David, it was unbelievably crass. I suggest you think twice before making such vile, hurtful posts. And find some "jokes" that are actually funny, while you're at it.
