If that's true, maybe it is a good thing if society stirs people into the right direction. So that when they find they want children, surprise, they "accidentally" chose just the right profession for it.

Personally I thought about income prospects when choosing a career. In my experience women are less likely to do so, which makes sense.

(Edit: can't write more comments - it makes sense because women have the option to have children and are not expected to provide for the family financially).
