Nursing is a highly acceptable respectable and decent paying job that is most highly associated with women and has nothing to with "salary" influxes related to men and women.
If a woman feels the above jobs are degrading to her...she does not HAVE to work them and go into nursing or other such fields. Having your morals influence what a woman can and can't do for a living is as absurd as having different salaries for males and females.
If I could get paid what those women do on stage or on the hunt...you can be damn sure Id be doing it instead of my "respectable" and moral occupation.
