p4b- all other countries pegged on the dollar (due to the world bank, or imf mostly) would be affected... it would probably be devastating in the undeveloped countries.

fish- you're right, the companies are benefiting.. from what i've read, mexico is being set up as the next big port, b/c its significantly cheaper than a port in the United States (all the 40k salaries for people and whatnot). China has its stake in this project, and it will drive down the cost of goods imported from china. This is why the highway from Mexico to Canada is part of the SPP as well.
