I think it’s useful to think of people who are unemployment has being forced out of the high productivity sticky-wage sector where they can work with lots of expensive capital to make pick-up trucks, into the flexible-wage scrounging economy where they can pick up cans, play guitar for tips, do odd house repair jobs, babysit for money, prostitution, deal drugs, etc, etc. Because these jobs are less productive, RGDP falls. And because they pay less than regular jobs, some people who aren’t desperate will rationally choose to watch some TV instead of working. That would probably be my choice (internet, not TV.)
