I did read the article, and the way that these people (they're all upper-class women, no SAHDs) are paid for their work strikes me as demeaning. If two people have kids, one of them is in the paid workforce and the other is staying home full-time with children, I have no problem with the idea that the SAH should be salaried out of the money earned by the spouse in the workforce. Pay the SAH a wage over and above the moneys used to run the household, for his/her exclusive use, and invest some of it into RRSPs and other assets, just like you would do with an outside-the-home job. I think this would bring a degree of economic equality and realism into marriages, not to mention making things a heck of a lot easier to figure out should the marriage end.
But this article was all about women receiving "wife bonuses" from their wealthy husbands - payments at the husbands' discretion based on how well the husbands deem that the wives carried out their homemaking and child-rearing functions. If they do anything other than be the perfect housewife, they don't get the bonus. That just creates far too much hierarchy and puts the husband in the driver's seat, in what should be an equal partnership. Not to mention that these women are S-C-R-E-W-E-D if the marriage ends. It's not truly valuing the unpaid work that SAHs do, it's putting them into a situation of dependence on the whims of their spouses. Yech.
