The cost of doing business includes all of that, so using a RMNB exchange rate 30-40% higher than current would likely erase all, or nearly all, of the advantage of the labor/regulation arbitrage. Once you include transportation costs and bad-will from China, your arb is gone. It would also, very likely, get close to eliminating our deficit (with some cuts, of course), as the tax revenues, not just from individuals but corporations, would skyrocket.
All other Asian economies are trying to devalue relative to the dollar to keep the arbitrage in place. The fact of the matter is that China is fucking with the global economy to bootstrap their shithole up to a 1st world country. They feel that it is their destiny to be superior to the west and that the west only "got there first", in their minds. Now they'll do whatever they can to catch up.
Personally, I would vote for the first President who would label them, unequivocally, a currency manipulator and do something about it, regardless of their affiliation or other issues. This is the single largest issue we have, without a doubt.
Until that time I fully advocate the Fed having QE2-X to keep exporting the inflation. If they don't want to play the game, be prepared to get fucked by hyperinflation, because without their currency floating, any inflation affects here are multiples worse there.
Saw this earlier this week, it's a good read and pretty much spot on.
