>a byproduct of wild wealth disparity, not because the rich are so generous with paying the government

you're overcorrecting WAY too far. Tax rate percentages are much higher on high income people, and THAT is why they pay most of the federal budget, it's forced generosity paying the government.

and it's actually the top 20% who dominate income and taxes, but including that extra 19% is important because that is the class of people ("coastal elites") who have a (all too human) tendency to rig the system in favor of their children in terms of good schools, universities, learning high status pasttimes, "internships" at prestigious institutions, rent paid in high value/opportunity areas after university etc. These high income people basically earn their livings from the 1%.

(that should not be interpreted as a pure sign of oligopoly, capitalist markets measure productivity, and that's how it works out, production in these industries is highly valued by the populace, but turnover of these people is high, where the top of the list is almost invariably new people each generation.)
