I mean, I would say that it’s far more ethical than most billionaires. She didn’t exploit workers, she performed and the populace gave her the money willingly. It’s as ethical as one can get in the modern day where no person can participate in society without benefiting from exploitation. And as far as I can tell from some half-assed searching, her investments are in property, but not in the landlord sense. She owns rich people property. Mansions and jets and shit.

I my personal opinion, musicians seem like the most ethical rich people in terms of how they got their money. They get exploited by the music industry early on, but money primarily comes from ticket and merch sales, which people choose to spend their money on in support of the artist. People hate capitalism, but forget what it is they hate about it and just start hating the money, forgetting why it’s bad- the exploitation.
