By what standard disadvantaged? For someone who cares about family the typical woman has things a lot better than the typical man who wants to be able to spend as much time as possible with the children.
I'm hesitant to consider "different life priorities result in different outcomes" as disadvantage.
I'm also hesitant to consider "overall x earns more than y, so lets make their wages even" fair when the jobs can be completely different.
Next thing you know people will start saying "Bankers earn more than McDonalds employees, lets fix the wage inequality by treating them the same"
Or "hey, that guy that took two years off to look after his kids, lets promote him over this other guy who's pretty much the same but stayed the duration"
Different jobs, different hours, and different life priorities end up with different results.
This "I am a victim" culture needs to stop. People should be treated only by criteria relevant to the task. Affirmative action is akin to an eye for an eye.
