You're clueless; central banks Don't fund the government. Period, end of story, it's not taught in current economics.
When the Federal government runs a deficit, they literally credit banks accounts of private institutions for expenditures over and above revenue. It's money created digitally out of thin air. The federal Reserve CAN NOT BUY NEW TREASURY NOTES! The only buy and sell in the secondary market to affect short term interest rates. Period, end of story. They have no secret power only to serve as a clearing house for the entire banking system. All the money they make gets remitted back to the treasury and it's not owned by a secret cabal of international bankers; it's "owned" essentially by all the member banks in the system.
Literally to the penny as a function of accounting, if the federal reserve "bought back" all the US debt, nothing would change in the economy. The amount of private sector assets would not change, only the composition.
Educate yourself. These federal Reserve conspiracies are laughable if they weren't so damaging to the national dialogue.

The proof in the pudding is what actually happens in the bond market. People who actually have money on the line do not operate on the conspiracy theory thesis of how the banking system works because it's complete and total BULL [censored].
Remember how quantitative easing was supposed to be the last gasp of the US treasury market and when it ended, the market was gonna crash? It RALLIED and has rallied ever since.
