I’m currently in the belly of the beast as it were, working for a company that manufactures stuff here in China for export to the US. In my defense, though, our company isn’t here to minimize costs-- our founder and president was/is a Christian missionary, and we’re as much a ministry as a business. Many of our employees are former beggars, ex-Buddhist monks, or handicapped people (who have a rough time in China); and a hefty chunk of our profits go to various local community development and evangelization projects (the rest is reinvested). Because we pay our workers well and provide benefits, our costs are higher that a lot of our Chinese competitors’, and we have yet to get any contracts with the big guys like Wal-Mart of Home Depot.
If the Yuan were un-pegged from the Dollar, we’d probably go out of business, so I’m a little ambivalent on whether it ought to happen.

Still it would probably benefit the US economy as a whole.
