Your comment is based on twisting the statistics.  Men and women in equivalent jobs, doing equivalent work for the equivalent period of time in their careers earn the same dollars, one as the other.

Many women have broader priorities in life than do many men who are focused solely on careers; as is their choice.  Why would it surprise you that any person of any gender who takes 3 to 8 years away from their careers often finish up lower on the totem pole, and earnings scale, than people who don't?

To test your hypothesis though, why not publish a job opening in the paper?  In that ad quote one pay scale for females and a higher pay scale for men.  See how that works out.
