My current hypothesis is that although the average salary and living conditions for men and women are becoming more equal, individual conditions are still not equal. The issue is that we are not dealing with just two groups (men and women) as some may suggest, but rather three: underperforming men, overperforming men, and women. This theory makes sense mathematically and historically, and there is a lot of evidence to support it. The equalization of salaries is in the interest of the women's group, and even if the average is achieved, the overperforming men's group could still have better living conditions and higher salaries by colectively punishing underperforming men.
