For financial discipline it does not matter, government will borrow anyway because it can, and it will print money anyway because it can. Because borrowing and spending is politically easier than not spending. US government does not have any savings - taxpayers are its savings account. And as long as substantial amount of people think that raising taxes is a way to solve the problem of runaway government spending - this savings account will be used and abused endlessly. There's no reason for politically risky cuts if you could just borrow and tax.
The sad fact is US government is addicted to deficit. And no addict was ever cured by giving them access to more of the source of their addiction.
