Having been in both sides of this, it very much seems like women are paid less, but I do not think this is a bad thing. Less pay mean more women get hired.
As an employer, $8 an hour for women or $10 for men means for $80/hr, you can hire ten women or eight men. For many lines of work, this is a discount often coupled with a less aggressive personality.
As a man, I was expected to do alot of heavy lifting, and there was a sense that I wouldn't be hired as easily for entry level jobs, because people expected me to be macho and take charge (I had someone literally expect me to want to be in management).
As a woman, they were more inclined to hire me, and I found some desk work, rather than yet another heavy lifting job. So in some ways, I was proud to have a lower wage. It meant I passed.
