Possibility 1: Female-dominated fields discriminate against men.
Possibility 2: Those fields are female-dominated because they can't get into male-dominated fields.
So what do the pay and prestige look like for female fields, vs male fields? Well, take medical. Nurses (low prestige, low pay) are >90% female. Doctors (high prestige, high pay) are about 70% male.
This suggests to me that there's indeed a huge level of bias and discrimination, but not in the way you think.
