I think you're the first person to hit on the key element here... the economy is no longer geared to a single-breadwinner family, but rather to a two-earner family. Thus if the man alone works, he'd better have a damned good income to support a family at modern middle-class standards.
Exactly..I really use to think when watching the Brady Bunch that here's a man who is an Architect supporting a family of 7 wife and 6 kids plus a maid! they live in a very nice house and everyone seems to live pretty much a middle class lifestyle, this is not possible in 2006.
Mrs Brady would be working full-time thier would be no maid and the kids would have to get a part-time job if they wanted all the latest toys in technology. (Computers, Cell phones, Blackberry's, plus cable TV, videos etc..)
So make some sacrifices.
What the hell is wrong with people?
