There's no need to tax anyone's income, just tax transactions, including Wall Street and Forex trades, and the US federal government would take more than enough money out of the economy to keep inflation at bay and maintain the value of the dollar. No income taxes are required. I say this as a far-left socialist who doesn't have much positive today about capitalism.
There are many ways to take money out of the economy, avoid hyperinflation, and preserve the value of the currency. Sales tax, property taxes, licenses, and permits, and government-run/publicly owned businesses, encourage the public to save money or invest it in treasury bonds and other investments..etc. Income taxes didn't exist until the early 20th century, around 1913.
When you claim that the government can't run without rich people funding it, you're just unnecessarily feeding their egos and giving more ammunition to the right-wingers who don't want the government to do anything other than bail out the rich and fight wars. You're only strengthening the right-wing rhetoric, pretending our federal government needs the rich's money to fund itself. It doesn't, we have a modern, sovereign, fiat currency, no longer tied to gold.
Our nation's GDP determines what our federal government's budget is going to be, not the wealthy elites paying their income taxes. Stop arming the right with these bad arguments and misconceptions.
