Taxes. I’m sorry you suffer from memory issues but it has already been explained to you that Americans pays thousands a year just for insurance coverage. That money is available to pay the taxes required.
You as a socialist apologetic wouldn't mind been taxed the beejesus out of, but when it comes right down to it, I very much doubt most Americans would be willing to pay perhaps 70-80% of their hard earned on taxes. For a start, it would destroy incentive for one to try to better themselves.
Remember that Capitalism is not perfect, but it sure beats the hell of any other system of government.
Most Americans would be ecstatic if they were paying 70-80% a year in taxes. It means that they are earning at least $10 million. So that's an easy 2-3 mil in the bank.
