The 8 hour work day was quite a victory but since it happened long ago i would really like to see how health and productivity in each occupation declines over time and by task. I expect not just the obvious jobs to have quite absurd numbers and vary a lot from person to person. One might imagine a gradually increasing hourly rate, a decreasing one or a combination of the two. Writing code i could probably do 2x an hour per day. Much respect for those who can do full days. If we imagine there to be roughly 500 defined occupations it seems quite doable to measure how "easy" coding really is.
