Considering women obtain degrees at a higher rate than men, I'd say there's just as much opportunity.
If you are alluding to family constraints, having a family is a choice. I'm a man with a family and I have seen many opportunities disappear as a result of my decision to have a family.
But how many women are afforded the opportunities to attain the job and life experience it takes to make as much as a man at the same job?
Once again -- stop thinking equality and start thinking equity.
