In America, the top 1% controls like 30% of wealth and the top 10% control like 80% of wealth. So even if you JUST evened it out a bit in America, that would make a big difference for the average person in terms of free time and financial security, but still not remotely to the point where everyone could focus on being an artist or doing something that fulfills a passion but doesn't pay anything.
Which is better for society, one person getting their dream job through their parents or five people getting an extra day off per week?
I'm more referring to the fact that a lot of jobs can be automated if we chose to go down that path. Or the fact that the majority of office workers spend half their day appearing busy rather than doing any work, due to the concept of the 40 hour work week.
And this is ignoring the fact that there are too many people being underpaid by mega corps, forced to work multiple jobs just to survive.
