This is not necessarily a good thing as unions basically underpay star performers and overpay bad performers. whether or not that is a good thing is your own opinion.
No. Male nurses make way more than female nurses, on average. A big contributor to this is that male nurses are far more likely to be CRNAs than female nurses and CRNAs are the highest-paid nurse specialty (and requires a graduate degree).

So male registered nurses in the US appear to be a solid single digit in terms of percentage. Wikipedia says 6.6%. The internet says CRNAs are 41-43% male.
So a very small number of male nurses, and a majority of them becoming CRNAs, and so the average pay for male nurses is higher than the female average. But really, I bet the 59% female CRNAs are being paid the same.
This is the problem with looking at averages only. If men are being prefered over women in the CRNA program, there is a problem. If female CRNAs are paid less on average than male CRNAs there is a problem. But the average alone tells you nothing. It definitely doesn't give you enough information to show you which part needs fixing.
Do the men employed as nurses make less money on average than their women colleagues?
