It went wrong about 100 years ago. When the US economy was overhauled, the institution of the federal reserve system and the income tax. Since then the dollar has lost 97% of it's value. Also a notable contributary is the complete conversion to a fiat based currency in 1970(?).
If you are 35 or older you might remember when working class families could afford a nice living with only one person employed per household. People really did live like Cleavers and Cunninghams on tv, at least as far as economics are concerned.
I don't recall the Cleavers or the Cunninghams having a TV in every room VCR's, DVD players, DVR recorders, a cell phone for every member of the family, IPODS, Xboxs...
Cable bills, high speed internet, personal computers... I believe it is possible to live like the Cleavers, if you are willing to live like the Cleavers

Ps The Cunninghams rented out the room above the garage
