You have backward. The federal debt comes from spending more in the 50 states than it takes in. They don’t spend it all in Guam. This is why there are military bases in every state - and contractors too. They pay SS and other welfare benefits in every state. It all comes back and then some and the recipients are happy and sufficient in enough states. “And then some” is the federal deficit.
Actually - far from backwards - that is exactly the point I have been emphatically making for post after post: that the Fed spends a huge amount of money on the States that it does not have. (Otherwise known as “money it is not taking in.”)
Now that you see this point, do you understand that this money the Fed Gov does not have must eventually come from somewhere? - Like maybe future taxpayers?
