The wage gap is an antiquated idea
Well over 50 percent of all graduate degrees are obtained by women and the result is higher paying executive positions
If there is any wage gap it's because women are getting those degrees in crappy majors. A study was done of the best paying majors and worst paying majors and the percentage of males and females taking those majors. Here's what was found:
5 Best Paying Majors
1. Petroleum Engineering - 87% male
2. Pharmaceutical Sciences - 52% female
3. Math and Computer Sciences - 67% male
4. Aerospace Engineering - 88% male
5. Chemical Engineering - 72% male
5 Worst Paying Majors
1. Counseling and Psychology - 74% female
2. Early Childhood Education - 97% female
3. Theology and Religious Vocations - 66% male
4. Human Services and Community Organization - 81% female
5. Social Work - 88% female
So really it's a matter of choice of career as to why women aren't getting paid as much.
