[quote]Can anyone explain how letting the USD fall against other currencies would harm US savers? A dollar will still be a dollar, and increasing the price of imports a little would seem to counterbalanced the threat of deflation. People keep talking about deflation and what it will do to the value of savings. I really understand very little of this, and am starting to believe that the so-called experts don’t either. It would be nice to at least understand the theory.

I won’t pretend to understand all the in’s and out’s…but my take is:
It’s no harm if your retirement/future purchases are in USD denominated. If you are a “foreign” currency saver who will purchase foreign currency denominated things, then you’re screwed. The nice thing about teh US is that it is self sufficient for many thing, so if the world trade came to an end tomorrow, and the dollar was worthless, you could still buy American.
Deflation: a dollar today is worth less than a dollar tomorrow. It does not hurt savers, it hurts debtors. However, since future income also decreases (lower price levels = lower income levels), it limits what you can save and is very hard to, “fix”, since it is hard to get people to spend if they expect prices to drop in the future. Inflation of the kind you describe, only leads to stag-flation since the inflation is only due to changes due to supply-side costs, not due to increased demand. Same demand curve, higher intercept on p due to costs, same or worse output.
This is all smoke to appease a domestic audience, and at this point not a real option. Chinese officialdom is under intense pressure from the Chinese “net”. If you recall, the Chinese started these sovereign funds that invested in financial institutions too early and promptly lost several score billion USD. People are very upset over this. Also, since they have a half-baked understanding of trade and capital account flows, (which like physics for every flow, there must be an equal and opposite flow the other way), they feel like the US has borrowed money from them and now they are watching the value of their USD savings drop.
The reality is this is the natural outcome of using a debased currency to implement mercantilist industrial policy. You can delay the change, but you cannot avoid it unless trade patterns change – and why would they? China knows this so that is why they put in thing like the new labor law and let the RMB appreciate 20+%. However, this was insufficient given the trade patterns and actually we are in the same place in terms of true value of the RMB. The longer you delay, the bigger the magnitude of the change. Well, here we are, the change has come.
