Such striking social inequalities should breed resentment toward wealthy American interlopers.  But for a large number of Mexicans the opposite is true:

Many Mexican waiters, hotel workers, and housemaids see an opportunity to escape poverty through these desperately needed jobs. Although their pay is low by American standards - in Mexico these workers are making a living wage double or triple what they would make normally and are able to feed their families, send their children to school, save up to buy their own homes, and eventually ascend from poverty to the lower middle class.  Many locals feel that foreigners bring to their country a lift to the quality of life and opportunities for their entire town. While they might be maids or waiters today they hope that their children will be managers. 

However not all locals feel that way... 

Native environmental activists are outraged that aggressive American developers don’t care that they are getting rich off the degradation of their home, one of the most majestic landscapes in the world.  They are ready for a showdown - not just with the developers but with their own people who scream at them to “shut up-we need the jobs”  to which they answer “but at what cost?”.
