So if a devalued currency is so bad, why do we complain about China doing it? Oh, because it makes their exports more competitive and all the jobs and money flow from us to them.
So far all the HYPERINFLATIONOMGzWTF!!!1 has been Wrong Wrong Wrong!
Consumers/everybody are awash in debt and trying to deleverage. No spending, no buying, only saving. Ergo no business growth, no jobs, no wage growth.
Inflation and/or weak dollar are bad if you are interested in overconsumption. Want strong $ to buy cheap gas to drive around in huge steel monstrosities. Want cheap Chinese shit to fill your 5000sqft McMansion built by Mexicans all bought on credit, refi's and home equity loans.
We've had that. Has to go the other way to correct. Need to be more competitive and have better trade balances. Inflation would help drive down real costs of our debts.
We can do it the hard way, or the really awful way.
