"Have I wondered"? Sure. Hardly a convincing argument though.
The question is, can it be quantified?
How much exactly are we "stealing"?
The US government has already issued a statement, saying that China is NOT a currency manipulator. Let us see if Japan can take a line against Uncle Sam.
"Have I wondered" was surely not the argument. But I am sure that the message got thru. Re US declaration, why do you think the Vietnamese devlaution happened?
