You're right. We only increased exports to Mexico from $41.5 billion in 1993 to $120.3 billion in 2005.
Like I said all you free traders do is generalize. You reckon you could break that down to agricultural commodities and intra-company trade?
I noticed where Ford has plans to invest $9billion in a Mexico plant. That is more money than Cintra has invested in a half million acres in Texas.
