Some analysts say the USA is about to encounter a massive bout o deflation. Japan has been trying to reinflate its economy for over 20 years, often with 0% interest rates. Hasn't worked, won't work. When debt is too high people won't borrow money even if it's free.
Some commentators such as at The Automatic Earth state housing in the USA will fall about 90% from peak to trough. Only a quarter of the way there so far.
If US leadership does go nuts and has the Fed monetize all the debt, I would be invested in gold, silver and weapons. No use holding a USB stick when hungry, angry, riotous hoards come visiting your middle class abode.
Heh... The JAPANESE won't borrow free money when they're already in debt...the Americans? They'll have inflation
