I’m not sure which “pill” I’m about to take but I really think what you describe is less “sexism” and more “human nature.” I’ve seen attractive men and women get promoted on the basis of their attractiveness and sex appeal. It is especially prevalent in customer-facing roles. For some reason, people buy more from attractive people. They trust them more. They’re less likely to cancel contracts. They complain less. They agree more. Everyone just seems happier and more content. A slew of psychologists have a lot to say about this phenomenon so I don’t need to rehash it.

I think sexual appeal is inextricably linked to being liked, for good and bad. Some people are born on third base. Some people need to work much harder to be funny and charming.
