Regardless of identity background, if you have a stay-at-home wife who takes care of the kids and family, while you pursue and grow your career, and can travel the world for work — worry and guilt-free — that’s a huge advantage many men have over mothers.

True. but it misses the point. Those guys also have an advantage over men who have children and working wives. In a competitive world, the two-earner family is handicapped. We have tried to pass laws to limit those handicaps, but they really can't be eliminated. Gender specialization makes an economy more competitive. Under stress, we will revert to it.
