re: U.S. corporate CEOs are neglecting their fiduciary duty.

It's more a rhetorical question to make the point that the pay gap exist more due to the fact that their are more men in jobs that are in higher demand.

Hell, I see it in the engineering field. College engineering programs are begging for women to get into the engineering field and when women do graduate as engineers they are the first hired and usually the highest paid (entry salary).

I saw it 20 years ago when I graduated in ME. There was one woman graduate out of 32 in my class and it wasn't from the college of engineering's lack of trying to get women into the field of engineering.
