I think it is 100% realistic for Swift (and similar wealthy artists) to one day realize that her business model handed down to her is unethical and exploitative and take steps towards making amends. It’s mostly a matter of getting her exposed to the right conversations, either through public pressure or interpersonal relationships. Like how she started buying carbon offsets for her jets.
I also (naively?) hope/feel that there will be a domino effect. Once one massive touring artist starts making equitability moves for their staff, other artists might follow. Doesn’t even have to be Swift tbh, Coldplay or Bruno Mars or someone could set it off.
Looks like your stats are a bit out of date, Swift is in first place again: https://www.forbes.com/sites/conormurray/2024/10/08/taylor-swift-becomes-worlds-richest-female-musician-heres-who-is-right-behind-her/
But you bring up a poignant point. Maybe some of it is because of the whole jet thing from some months ago, those discussions were really raging on here and so it’s probably echoing forward.
