So basicly, let's deploy UBI, and if people want to work 3-4 day weeks, it is up to them. I agree with this idea, and it clears up the work-no-work part of my argument. I just felt that UBI is such a big step, that just lowering the number of weekly hours had a precedent (from 7 to current 5 days a week) and was not associated with a more leftist sentiment, thus being easier to pass.
Hum, do we really need to see this as white and black. Work or no-work? Why not just introduce 30 hours/week or even 25 hours/week. And by that I mean employees keep the same weekly salary, companies use the gain in productivity by automation to give back some family time to employees. What we get in exchange, is one or 2 extra days of consumer spending. People tend to spend more during weekends anyways, so everybody is a winner. We keep the same salary, we have an extra day free in the week, companies get the 15% increase in consumption, and get slowly ready for full work automation.
