Using the Mexico-US border, this article argues for an expanded definition of �tourist� to include those who travel to produce, and not only to consume tourist attractions. Millions of people have crossed the Mexico-US border to contribute to productivity, and much of it their productivity supports the tourist industry in the United States. With this expanded definition, the article goes on to examine what this means for both kinds of tourists�leisure tourists and work tourists. It also describes the dialectic between the two and how that dialectic relates to the world capitalist system. Mike Davis (2005) called it The Great Wall of Capital. Teddy Cruz wrote of �an imaginary line along the U.S.-Mexico border and extending it directly across a map of the world, what emerges is a political equator� (2008: 111).
Wendy Brown (2010) noted that walled states coincide with a global waning of state sovereignty in which states use fences and walls instead of recognized and legitimated authority to control their borders. At the same time, travel in general and international travel in particular feed what arguably has become the largest revenue producing global industry: tourism and hospitality.
