> Taylor Swift's claim to fame is that she is an attractive white woman from affluent parents, who is both highly malleable and a very hard worker.
Swift's success is about much more than that. Fundamentally, she is targeting a market segment her competitors have left wide open. Her persona-- a hard working, self-deprecating, people pleasing young woman trying to navigate relationships--is immensely relatable to a huge number of young millennial women. That's especially true because Millennials are just more square than Boomers or Gen X. They are more inclined to follow social expectations, and have fewer vices than Boomers or Gen X at the same age. Swift's clean lyrics thus stand out in comparison to her contemporaries.
That also makes her more appealing across generations. I've been a Taylor Swift fan since the beginning, and I'm happy to spend $$$ taking my 10 year old daughter to one of her concerts. I'd never do the same with someone like Ariana Grande or Lizzo or even Beyonce, whose music is more sexualized and profane.
You should watch Miss Americana. Swift runs her operation like a business. It's quite amazing to watch.
