I agree entirely with the proposition that wives work very, very hard and aren’t appreciated enough for it (and no, that’s not me blinking t-o-r-t-u-r-e as I read from a prepared statement). But this write-up of a Salary.com gimmick just seems like a pinata of bad economics to me:

NEW YORK – If the typical stay-at-home mother in the United States were paid for her work as housekeeper, cook and psychologist among other roles, she would would earn $138,095 a year, according to research released Wednesday.
This reflected a 3 percent raise from last year’s $134,121, according to Salary.com Inc , Waltham, Massachusetts-based compensation experts.
The 10 jobs listed as comprising a mother’s work were housekeeper, cook, day care center teacher, laundry machine operator, van driver, facilities manager, janitor, computer operator, chief executive officer and psychologist, it said.
