Yeah, and given the results of the past decade I'm inclined to trust the Communists... Not that they're actually communists; they're just a really big national corporation, imho.
China, not the Fed, has ultimate control over their monetary policy. They can always change their monetary policy and probably will have to. Which is what the discussion is in fact about, if you read the original article.
If the Chinese keep up their peg, holding RMB is equivalent to holding dollars.
If they fail to maintain the peg, the RMB will most likely rise. Most US consumers are already exposed to the downside of this risk - they have expenses which will rise if the RMB goes up (e.g., all the goods they purchase which are made in China).
Why would you need to visit China to have an opinion that could be arrived at by looking at financials - a common practice in measuring success. Just look at a portfolio of large Chinese companies - they are doing well, thus I would also hypothesize that they are well-run companies.
Chinese firms are riding a huge wave of growth driven by wage differentials. In this macro context, it's easy to make a lot of money with poor management.
