Yes, but [hyperinflation] is better than the US Great Depression.
I'm not sure I agree with your statement entirely (ie. the choice is "Wiemar vs Great Depression"). I think the macroeconomics are much more complicated this time around. I do agree that Kondratieff Winter will be the end result. Here is how I see things...
The Great Depression was deflationary depression when the US was on the gold standard and was one of the largest creditors in the world. The value of "money" (cash, gold, etc) went up and the value of "credit" (debt) become worthless.
This time around we are net debtor to the world and most of our inflation has been exported to foreign soverign nations. Credit and equities are rapidly deflating, but there are an inflationary net worldwide food and energy effects. And all those dollars are stacked up in China, Japan, UAE, Saudi Arabia, etc just waiting to come home.
The Federal Reserve cannot prevent credit deflation because it cannot print confidence. Nor they can prevent the slowdown in the velocity of "money". At a certain point the paper will park itself in precious metals or tangible assets, which in a sense is a decrease in monetary velocity (deflation) as gold and silver begin functioning as money. You can also view this trend as the "crack-up" and an increase in the velocity of 'cash (paper)'. On the other end of the scale , 'Debt' (ABCP, CDO, etc) velocity will grind to a halt. The Fed can only control the macroeconomic "see-saw" effects to a very superficial extent.
So we will see extremely powerful inflationary AND deflationary forces. The Fed really cannot do much here except slash interest rates and pray to Lucifer or whatever evil they worship.
Why the Fed is powerless and what is net effect?:
1) The shadow banking system (much of the banking system is non-depository institutions such as hedge funds which cannot borrow from the Fed). [Deflation]
2) The problem is not one of liquidity but one of solvency (the entire system is bankrupt). [Deflation]
3) Consumers attitudes towards debt are changing. (you cannot force people to borrow). [Deflation]
4) Credit derivatives >$600 trillion (credit default swaps, based on confidence). [Deflation]
5) Counter-party risk (Will your 401k go under? Will the 'other bank' pay up?) [Deflation]
6) America's monsterous debt requires foreign cooperation to service (Will China play nice?) [Hyperinflation]
7) Will there be national bailouts of the major banks? ("Citibank: Too big to fail") [Hyperinflation]
8) Will there be nationalization of MBIA, Freddie Mac, Fannie Mae, etc? ("Implied guarentee") [Hyperinflation]
9) Will worldwide grain shortages continue to persist ("thanks chemtrails") [Hyperinflation]
10) Will foreign nations stop buying our debt? (rising long term yields) [Hyperinflation]
11) Will the Fed monetize the long end of the yield curve (print money to buy 10y notes) [Hyperinflation]
So you see there are many factors at work here... some are dependent on the Fed, some are dependent on Congress, some are dependent on foreign nation-states, and some are a bit random.
The effects are going to be very difficult to predict, but suffice to say the global economy is in very deep shit.
