"But wait," you say "How will we incentivize entrepreneurs if they can't earn more money?" For everyone making over $90,000 (approx. 11% of the population), their pretax salary is used to assign them national ranking that's publicly available, much like a ladder tournament, which could be subdivided into regions, industries, etc.
The rationale for this system is that we use one system - money - for two unrelated social purposes: reducing suffering and establishing status which incentivizes production. In my system, these purposes are less coupled.
The $90,000 number was calculated by dividing the total US income by the number of workers, so this would need to be adjusted yearly. If this system was applied globally, the average salary would be $25,000 which is quite a step up for billions of people. It means that today, humans create enough wealth annually so that every two-parent household on the planet could live like the American middle class.
