Okay, first day here and I already see I perhaps shouldn't have subscribed.
Anyone who thinks about it for a second longer than it takes to read it will see the problem - this rules completely devalue skilled work. An hour of sweeping the floor is valued the same as hour-long operation on sick patient. Except cost of becoming a doctor is countless hours paid to teachers, professors etc. while cost of becoming a cleaner is just a broom. Rewards is the same, so why bother? Why take risky job or something that requires upstart investment? In fact you would need to work years as a menial worker before you afford learning any skilled job... unless we add loans but with loans we explain why there are billionaires "I never did 10 000 hours of work, but I loaned my hours with interest"
Also - anyone who does farming will most likely notice that a daily intake of food necessary to survival will probably cost you a week of work or so...
I'm all for treating everyone fairly, but this idea is the kinda shit that starts dystopias.
