I always tell people - when talking about unemployment rate - that our target rate should be 100%. Many of the things I do for work I would happily do for free - and sometimes do.

Labor as a choice is a great outcome. You're not a woodworker because someone needs to be - but because you love it. So: if there is no work to do, it doesn't mean that work wouldn't be done, it just changes the motivation to do it.
