Women with College Degrees Earn Less than Men with No Degree

Why is it  that in 2010, that more women than men are attending college, yet college educated women still earn less than men?

I stumbled across this post , that women  with a community college degree earn less than men with no degree?

What kind of message does this send young women? That having a college degree doesn’t provide you with the same respect than a man with no credentials?

Also speaking as a woman in  technology, what message does this give? That careers in IT are not ideal for women?

This is all the more reason that visibility needs to be raised for women. If they are women than men in the classroom, shouldn’t that also be acknowledged salary wise?
