If a person is expected to only choose a high paying field, but has two options open:
1. High paying field they don't really like.
2. Low paying field they'd love to do.
Then if there are social expectations that someone must make a lot of money, they will generally be forced to choose option 1.
The argument that men are forced by social expectations to choose option 1, and women are more freely able to choose option 2 is not 'absurd'. It may be correct or incorrect and would need some evidence to back it up, but please don't go around labeling positions you don't like as 'absurd'.
