... If all we were doing is substituting production at home for production in the marketplace,' said Daniel S. Hamermesh, an economics professor at the University of Texas at Austin, 'then maybe unemployment wouldn't be so bad.'...In 21st century America two income families have a very significant advantage. The risk of going entirely without health care and without income is half that of a single income family. Risk reduction isn't the same as economic value however. It might be more efficient for one family member to work for money and another to manage home and health (more sleep, more exercise -> longer life, less disability, greater lifelong income).
From the perspective of the overall economy, being unemployed is not the same as being unproductive -- and it's the productivity over time that matters for some measurements.
