This is why we have a 19 trillion dollar debt.
Yes. It is.
However, you are wrong about the 19 trillion. It is at least 21 trillion and climbing fast even at insanely low interest rates. It is unsustainable and the only reason it is not absolutely disastrous to the US is that the condition it entails is shared across the globe and is relative. Relatively speaking we are still the strongest and most stable economy with critical mass.
