A related concept in economics is the Laffer curve [1], which describes the tax rate that extracts the most money from the population. If you tax everyone 1%, you collect very little money, and if you tax everyone 99%, very few people will work at all. Interestingly, the sweet spot seems to be in the mid-30s for the population in aggregate (which lines up with Apple's fees almost exactly), but is someplace around 70% for the highest earners. This implies you could jack up the top marginal tax rates to > 60%, and while most billionaires may grumble a bit, they will not ragequit from the economy.
