With significantly more capital and free time, you would be able to develop and manage your own projects outside of the workplace, allowing you to continue developing yourself, your skills, and your contributions to your field. If you prefer to put the majority of your efforts into a single project or workplace, incentive structures could be developed to acknowledge your outsized contributions while not imposing such as necessary for everyone.

I think you have a great question though, and things like that would best be answered collectively, through discussion and experimentation.

What do you think? What would you prefer? What would be fair to you to recognize your extra efforts? What checks and balances would be needed to have a 16hr week as the basis for a livable wage, while still allowing for people to work more when desired?
