Money Laundering. That is all this is. Illegal Ponzi scheme. They go to banks and buy parking lots for a billion dollars, or “loan” a bank a billion that then loans it back, etc. Illegal accounting gimmicks. There is nothing propping up half the national debt anymore. Half of it is owned by somene else but half is owned by the very people that issue it. The national debt is the biggest bubble ever and will not just pop but explode like a nuke when it goes off.
The only blessing will be if it takes out the Federal government. Unfortunately, like the cockroach, the Federal government will likely survive while the economic blast destroys us.
