What if you took people who have always had to work/chosen to work and give them resources to free up their time. Of course, you'd probably get a lot of bad things as well as good since sudden changes will always generate some churn and chaos short-term.
Think about this for yourself. If you didn't have to work, or only had to work 25-30 hours a week what would you do with the extra time?
Now apply that to every middle class individual. Sure some would spend the time in less productive or even harmful ways. But others would spend it even more wisely than you imagine yourself spending it.
