How about we fight back when China manipulates their currency to take advantage of us?

First we would need to stop manipulating our currency- and just allow the current depression cause deflation. Next we would need to raise tariffs on China to make up the difference between what the Yuan is vrs what the Yuan should be. I favor indexing tariffs to the cost of regulations while repealing the regulations with the worst cost to benefit ratios. If the clean water or Clean air and clean water acts are good pieces of legislation why not do what we can to encourage the third world to follow that path?
