” So even if evening the playing field were possible (which is doubtful), it would not solve the problem, it would just shift it to other girls.”
But if we could keep shifting it to younger and then to even younger girls instead of accepting that the older girls are continually left out (thereby getting older and having fewer options), we will have bought enough time to figure out a system where no one is left stranded (as the younger ones are still young enough for them not to have a problem).
