Quote from optioncoach:
First, the dollar will NEVER be weak enough for foreigners to move manufactering here versus overseas. I doubt a strong dollar is the reason manufacterers are in China, Vietnam, Pakistan, Mexico, etc... It is way cheaper in terms of labor and other costs and shipping good from so called 3rd world countries to here is still cheaper than making those products in the US.
Here is one interesting fact, for a long time who is the U.S.'s largest trading partner who imports the most to the U.S.?
You might be surprised to know it is Canada because most of the US auto manufacterers build the cars there and bring them back in to the U.S. (The trade gap with China, the second-largest U.S. trading partner after Canada, increased 13 percent to $23.8 billion in July, second only to the record $24.4 billion reached in October 2006.)
Also the ex-im bank supports financing of exports to make it easier for overseas entities to buy U.S. goods. Ex-im bank only serves those who cannot get standard private financing so it is not a means to weaken the dollar but simply provide financing.
This country is a consumer lead economy and if you weaken the dollar and drive import prices up the Fed will have to raise rates to fight inflation and the dollar will strengthen and this will go on back and forth.
