Anyone who understands math and statisics knows this site is bunk.
However, since you want to talk, it has been shown that when you compare men and women based on their actual job title and actual work experience, the pay difference is about 2 cents, or 98%, not 72%.
The 72% claim is apples to oranges and so statistically aweful that someone with a basic statistics course in college can see the mistakes.
You can't compare men vs women as averages across the board when they make different career decisions ON AVERAGE (what type of job, what field, what to do when the family has kids, etc).
Like manhattan said, companies bend over backwards to find women and hire women in management positions, but the problem at times is finding qualified women.
