Personally, it doesn't amaze me at all how important good looks are for a model. I know I'd prefer to look at a lithe college coed bounce around in Ibiza rather than a frumpy mother of three work in a textile factory. It's programmed into my animal brain.
It helps to keep in mind that "influencers" are a product of a lot more than good genes. It takes a large investment into beauty products, hair stylists, clothes, camera equipment, travel, etc. These people are constructed using their fit bodies as a foundation to build upon. Taylor Swift is a product, not merely a person. Her development costs surely tally into the millions.
