The only way to shrink Government is to starve it of revenue and borrowing authority.
Attempts to limit borrowing authority have failed via attempting to "cap the Debt Ceiling".
The Government will contiue to spend, tax, and borrow until the private market and foreign nations stop buying US Government debt instruments.
Nations are not abandoning the dollar, yet. But they are de-risking from the dollar by diversifying into other stores of wealth (currencies and hard assets), and reducing the amount of US debt they purchase.
At some point, the giant sucking sound of buyers heading for the doors, at Treasury auctions, will be too great for the Fed to continue to manipulate US interest rates.
The ratio of dollars to GDP is out of balance, but can be brought back into balance by gradually shrinking the money supply, growing GDP, and increasing the velocity of money via increased, inefficiency-positive capital investment.
Good luck with that, Swamp Monsters.
