As the parent of a brood of starving artists I can sort of see the point of saying that if Taylor were a true, oh so good and wholesome, artist, she'd not be doing what she does and making millions and flying around in jets and so forth. I like to say that my favorite artistic muse is Vivian Maier, who worked all her life as a nanny, and was discovered only after her death to have been one of the greatest street photographers of the 20th century. But like it or not, Swift is not that. She's an entertainer, and the visible part of a huge and lucrative industry. Sure, she's a talented songwriter and performer, and coincidentally quite easy on the eye, but she works that vein and works it hard.
It's always fun to mock and disparage movie stars who make millions per picture, and sports stars who make incredible amounts of money for tossing a ball around, and so forth, but I think if you look at the industry that surrounds them and the profits that are had because of them, their reward is proportionate. It may be a proportion of something you disapprove of. It may well be that in some utopia nobody would get rich and we'd all be happy amateurs and artists, but we've yet to see that working. Not everyone is at home in the Bread and Puppet Theater. And it may well be (I would agree here) that billionaires and their ilk pay too little in taxes and as a class are over-privileged, but that argument is about what they should do with the fruits of their work, luck, talent or fame, and not the work itself.
