In terms of the pay difference in undergraduate pay, is that comparing against the same degree/field of work? Reason I ask is because there are some fields which are male dominant eg engineering, which would have higher paid graduates. Where I work they are wanting to encourage more females to take up science and engineering degrees to bridge the gap. This is great I have no problem with that. However if women actually don't want to choose these subjects and are just not enrolling then you can't say that it's because there is gender inequality.
I know I cannot always articulate myself very well and I have probably confused feminism with gender stereotypes. I just feel that in today's society (in australia) women have lots of opportunity they just need to want it and go for it.
