Look at it a different way.
First define our current environment.
1. The ME3 are picking our pockets and their influence and dominance continues to grow thanks to the Government/Crown subsidies as well as sweat heart deals from Airbus.
2. All Chinese businesses continue to flourish due to 4 factors: our extreme debt to China and China's manipulation of our currency, as well as China's stealing of intellectual property and their ability to not only be competitive in manufacturing, but dominate the sector. (those manufacturing jobs used to be in America).
3. NAFTA continues to hurt the US and Canadian economy in terms of movement of goods as well as relocations and closing down of over 70,000 factories from the USA.
4. NAI type carriers will continue to pick up steam. Combine that with the airborne version of NAFTA, ie (open skies) and you can see big storm clouds coming.
So.........Which trade deals currently in place help the USA's economy? Which ones are beneficial to US jobs? Which one's help both our strategic influence as well as our economic influence?
Now that we've really looked at the lay of the land you can better scrutinize which trade treaties should be eliminated, or modified, and further what line-item changes would the various economists recommend?
