I disagree. I think you'd find a substantial majority of families would love to be able to keep one parent at home, while the other worked, if it were financially possible. Doesn't matter which one.
I'm in Canada, so I can't comment on US tax burden, but our tax burden from lower middle class and up is effing rediculous. I'm not a rich man by any stretch of the imagination, plain old middle class, and my burden of tax last year, according to my accountant, was 56%. Thats all taxes: carbon, income, municipal, sales, E&H, ad nauseum, ad infinitum. Its damned rediculous, and its one of the primary reasons why both parents have to work just for basic needs, much less to have any other kind of "excess".
