The Fed should be attempting to smash the cost of US Government debt to the floor so the treasury can issue 50 year paper at 1.x% while there may be a window to do so.
It would be very unpopular with the wealthy and the private US financial system. I believe it's the sole reason they're not working aggressively to minimize what the US is paying for its debt vs other more risky nations. The Fed views the private financial system as a critical partner. To an extent by intentionally leaving borrowing costs higher than they have to be, they're performing a middle ground compromise with those partners vs the government's fiscal condition.
