Well, "forever" may be an overstatement. Can we agree on "for as long as the Central Bank, i.e., 'the government' wants" as a substitute. And yes, I think it is proven. Consider Japan for example.
I sense that you're wanting to insert party politics and ideology into the discussion, but I'm not biting. Not today anyway.
Interestingly, there is at least one rather radical U.S. economist that has said holding rates near zero indefinitely would actually work out fine. I don't know whether I could agree with that or not because I haven't spent any time thinking it through.
as a support for your views that interest rates should be kept low for the masses, as for people who get by from paycheck to paycheck.
I admit my memory isn't what it used to be, but frankly I can't recall ever having expressed that view, or even ever having thought about that. Perhaps you can refresh my memory. Or is it your memory that is faulty here?
One thing you alluded to that I think I can go along with is the danger posed by populist politicians if they are allowed to interfere with Central Bank operations. I believe very strongly that the C.B. in every nation should be shielded from political interference. The Rand Paul 'audit the Fed' Bill was an attempt to give Congress greater oversight over Fed policy. Very dangerous in my opinion. I don't have confidence that the average Congressmen's understanding of money, finance, and central bank operations is any better than the average 'elitetrader' participant's knowledge. It seems the average Congressman would be unqualified to be given veto power over or to dictate Fed policy decisions. That's the reason we have the Central bank structure we do. It's a specialty area of banking that requires highly specialized knowledge. Of course the Congress has the final say because the Fed is a creation of Congress. But do we want the Congress interfering with Fed policy decisions or day to day operations? I don't think so!
The kind of audit intended by Paul was not the usual kind of accountant audit, but something else entirely. The Fed's books are now public and available to the world, which is one of the reasons the Fed is so much respected around the world and why central bankers everywhere trust the Fed and are willing to work with the U.S. Fed. And naturally the Fed is audited several times over, both internally and externally, and more or less continuously. The auditors' reports are in the public domain.
