The US dollar is self-funding and it will buy whatever is for sale denominated in dollars without creating inflation. Taxation (and borrowing) are disconnected from any fiscal constraints and spending/inflation is entirely a matter of resource availability, not the quantity of money.

Should the voters ever discover that any suffering they experience that could be mitigated by creating more dollars is entirely a political decision, not economics, the wealthy would wish that higher taxes were the only thing they, and their purchased politicians, had to fear.
