@MisterBlueEyes: I have seen the “study” but it wasn’t really a study. They simply took all of the roles that the typical “housewife/househusband” would perform (private shopper, chauffeur, tutor, chef, housecleaner, etc) and added the annual salaries of those positions that they chose.
Back when they did it, (I think it was in the late 60’s) the annual full time salaries of all those things added up to whatever figure they gave. I don’t believe they took into account the percentage of time and divided.
That said, if there was someone willing to pay my wife for all the work she does, which is probably was more work than I do at “work” I would welcome it.
