Ever wondered how much money you (or your mom) would make if paid for all the "work" done as a mom? Salary.com has a wizard that can help put a dollar amount to the "mother" job. I found out about it on a mother board, where a few mothers responded with their supposed "salary"... up in the $100-200k range!
My total? $35,000. Am I a terrible mother? Or efficient for getting things done in less hours? Or lucky to have an involved husband? Perhaps a combination, but the point is still there: mothers hold a valuable role even if that value is not returned in dollars.
