I thought you were going to say ..."both parents working.....to a Female working household" That's what's happening......more males lost their jobs in the current recession and are still out of work.....females have fared much better.
Add to that the kids are strapped with college debt and can't find good jobs. This is not progress. When I got out of school in 1972 jobs were plenitful, When my first recession hit in 1974 it last a few months and again in 1981 when I had a 14% mortage but the recessions did not last years. Market went down based upon fundmentals.
