"some unknown reason"
To me there's nothing unknown about it. It's the globalist exporting of our economic base while at home the economy implodes. I have to laugh though at how all the Clintonites are bashing CAFTA but conveniently forget how CLinton pushed so strongly for NAFTA. There's hypocrisy everywhere on this.
It is interesting that when NAFTA went through most of the outrage came from the Left. Years later though, many patriotic, heartland communities are feeling the sting and speaking out against it.
