That's highly Unlikely. Mexicans that live in the states are proud to have mexican roots but they wouldnt want to be part of Mexico, they live well as part of the United States and they feel proud of being american citizens -at least the legal ones-, they want to assimilate and follow the american way of life. American culture enriches with cultural elements of mexican culture without american culture stop being the main and most important culture to the United States, Mexicans dont want the USA to become Mexico but they make a contibution to that culture. Cheers.
