Every political system has patrician and plebeian tracks. In America, the former can be bought (versus solely inherited). Being a politically-active patrician in New York involves an expensive list of patronage. That’s where the power players are, and that’s where you’ll cut casual deals.
It’s optional. And it’s different from civic responsibility. But unless you think the status quo is hunky dory, you’re going to want to change things, and the cost of access varies geographically.
I’ve seen billionaires quibble over ca. $25k tables. And $300k gives you enough to, outside tier 1 cities, access, if not be kingmaker on, state politics on the patrician track. The cartoon impression of American high politics is stupidly off, starting with how coördinated it presumes the system to be.
