If she lowered the price of her tour tickets it would just increase demand (without a commensurate increase in supply, since concert venue size and the number of shows she has time to put on both have limits) and thus further enable scalpers.

Lowering the prices of music sales or merch would be more feasible, but would be relatively complicated due to messing with supply/demand/product quality/employee & supplier compensation, etc. (For example, it could arguably be better to keep the merch prices the same or even raise them, but have the manufacturer increase worker wages or something like that.)

Rather than sit around hoping that she more fairly allocates profits of her own accord, if the societal goal is to prevent billionaires then the easiest way to ensure that would be via government policy, by increasing her income tax.

So, two things: I never said people should be billionaires, I said there's a difference between her and Bezos. You can't pretend that a $12 album, or Spotify streaming costs are the same as making people pee in jugs for minimum wage. One of them is actually doing things that people like in exchange for money, and people are saying "yes, I would like to spend my disposable income on this luxury good" often enough that she has more wealth than she can ever spend. Extracting wealth isn't the same as exploitation.

Second, if you exclude the value of her music catalog, she's not a billionaire. If she sold every piece of real property she owned, and gave away every last penny, he net worth would still be in excess of $500M on account of that. It doesn't seem quite fair to say that someone is terrible because the things they made are worth more than an arbitrary line of "a few million". Saying that someone is hoarding by just owning something they made that people say is worth a lot of money is judging someone for something largely out of their control.

None of this has anything to do with someone being "left leaning" in any case. Left leaning isn't some short hand for ethical purity of being a member of the proletariat or even the working class. Saying that someone who publicly and materially supports progressive causes is "left leaning" seems pretty fair and reasonable.

I don't particularly care about swift being some bastion of goodness. I also don't actually care if someone has a billion dollars. I do care if they exploited people to get it. I care if they exploited people to get less than a billion. So lumping people together by the number without focusing on the conduct misses the point.

Very well put
