In dual entry spreadsheet accounting (the system used worldwide to track money) there is always a "source" and a "destination" that remain separated by sectors. The "ONLY" net source of US dollars is the deficit spending of Congress as it provisions itself and pays for its programs and infrastructure.

It collects taxes, not to "fund" its spending, but to create a denomination for its commerce with the private sector (the destination for money) and a need for its currency/unit of measure in the economy. You can trade in seashells or cow dung if you want as long as you can make the tax man happy with the currency he demands. If not, you lose your property and may even lose your freedom.

Every dollar Congress spends above what it collects/destroys in taxation becomes someone's monetary asset in the private sector. It can then retire private debt, settle contracts, and be net saved. A "balanced budget", the holy grail of politicians and other idiots, represents the theft of all of the resources and labor the currency issuing government uses, clawing back all payments for those in taxes. "THAT" is what is not sustainable.

Your federal government doesn't "need" your money and certainly doesn't need to borrow it back after creating it. What it needs is for you to need its money and that means allowing some reward for provisioning that government upon its request. Is $30 Trillion too much money for the private sector to show for its net accumulation of the government's money since our nation was founded? We can have that conversation, but it must be from the perspective of our fiscal reality, not the nonsense myths and scare porn propaganda this piece represents.
