Have a nice ceremony and present a medal for winning capitalism.
One million dollars and not a penny more. Enough for most people to live comfortably, but not enough to buy governments, or for the upper classes to never need to work again to maintain their lifestyle and privilege.
No human being needs or deserves a hundred million dollars.
But the point is kind of to eliminate the upper classes and scale the economy back into the reach of most people. So there would be no FAANG salaries. The cost of everything (healthcare, education, housing) would go down. It would place a hard limit on political influence that isn't too far out of reach of current Congressional salaries and would probably limit pork barrel politics and insider trading as well. It would end inherited wealth and maybe even limit the length of copyright.
That's an admittedly naive and utopian view and I'll admit there are bound to be complexities and externalities I'm not taking into account because I'm not an economist. But it's either that or we seize the means of production and put the rich to the guillotines until the sewers choke on their blood. And then something something luxury space communism.
