Does North America Exist?

In the early 70s, when I was a graduate student at UCSB, I was appalled at the level of ignorance of  Americans about Mexico. Tijuana was there just a few miles away, and all I could hear from the students was how interesting Europe was.

Then came NAFTA, and I got all teary eyed about my future as a Mexican  with an American PhD degree.

That treaty was only good for Wall Street types on both side of the border, o yeah we have those types in Mexico.

So, is there such a thing as North America?

Obviously geographically the answer is yes, but mentally Mexico does not exist in Many Americans eyes.

UNTIL DONALD JOHN TRUMP VISITS MEXICO TODAY!
