"With two-income families now the norm, and both men and women working a record-breaking number of hours, the question has become how to accomplish what used to be a wife’s job, even as old-fashioned standards of household management and entertaining have been relaxed. Many men are sharing the work of chores and child care with their wives, and some do it all as single parents, but women still generally shoulder a greater burden of household business (or fretting over how to do what is not getting done)."
"Households often opt to stay put rather than default, leaving them trapped in places with high unemployment and unable to move to where jobs are plentiful. The rise of the two-income household has also made workers less mobile than they were: it is harder to move in search of jobs if there are two careers to consider."
