Since gender only seems to play a very minor role in wage differences between men and women, as opposed to say, willingness to work full-time/overtime, personal

Since gender only seems to play a very minor role in wage differences between men and women, as opposed to say, willingness to work full-time/overtime, personality, and job choice, it is not at all clear that the 'gender' pay gap is a problem that needs tackling. I believe systems that strive for equality of outcome and put group identity above individual qualities will only create more injustices, not fewer. If the current situation we have is mostly the result of men and women using their freedom to make different choices in life (on average), then forcing different outcomes with these systems seems like an even worse idea. The assumption that equal work deserves equal pay is fine. But who decides what equal work is? There are a lot of factors that can make one employee more valuable than another employee in the same role, and therefore it only seems reasonable that companies get the freedom to reward those employees differently. All these subtle factors will not show up in the data, and so I do not believe it will help with anything, except for making people see problems where none exist.
