The woman is compensated because of lost economic opportunity because she left the workforce and worked in the home. In the NYC market a woman technologist making $100,000/yr can expect that salary to go up by 50%, at least, in 20 years. She leaves the workforce to raise kids, kids grow up and she and her husband get divorced. She is not getting a 150K job. She may not even be employable in her field. Hell she may wind up as a cashier someplace. That's due to a decision that was, presumably, jointly made by her and her husband. You don't believe her former husband owes her anything to make up in part for the money she cannot earn because she was out of the market raising their kids?
And I'd point out anyone who suggests raising kids and taking care of home is not "working" is naive at best. I assume you don't have kids so you may not actually realize this.
