Getting back to the original subject, the key question in my mind is "where is our competitive edge?" First, I consider Europe to be in the same mess as we are, so my comments relate the Western developed countries to the rest of the world.
Consider that our wages are by far the highest in the world (even adjusted for the weaker dollar). Our housing costs are still extremely expensive. And food, and vehicles, and gasoline, and electricity, and everything!
Yet, thanks to the WTO and treaties like NAFTA, we trade on an equal basis with countries like Mexico, China, and the rest. The cost of living in all of these countries is much lower than ours... the cost of labor is cheaper, the cost of land is cheaper. Of course they are going to import things cheaper.
If you take your dollar overseas (not Europe), your US dollar is still amazingly strong. It is not as strong as it used to be before this recession, but the dollar still has some abstract intrinsic value. I guess people think the US government is stronger than other countries - so they assign a higher value to the dollar.
What we are seeing now, and I think we will continue to see in the future, is a falling value to the dollar. Or put another way, the assigned value of our assets (in dollars) will continue to fall. There is no reason why the cost for a medical operation in someplace like India or China should be 10 times cheaper than in the US. There is no reason why the cost to produce Nike shoes should be 10 times cheaper in China than in the US.
As the world globalizes, the
purchase power parity should start to equalized. That is, for a given "basket of goods and services" every currency should buy the same amount of stuff. Right now a U.S. dollar exchanged and spent in India will buy more haircuts than a dollar spent in the United States! (To use a simple example). I see no compelling reason why the US dollar is as strong as it is.
I see the US dollar continuing to inflate (ie, loosing value), and anything that can be traded on the international market (like food) will continue to become more expensive.
