In all fairness, most Mexicans in Mexico are some of the nicest people you'll ever meet, obey the law, and just want to live a good life. The problem is that the ones who are willing to break laws to illegally cross our border are also more likely to break other laws. This is just common sense. They do have a right to complain about a cultural shift, just like we have our right to complain. Mexico City is huge, but it's obvious certain neighborhoods are changing. Cities like Puerto Vallarta, Lake Chapala, Mazatlan are changing. Cancun and Telum have always been tourist areas and not really authentic mexico. It's an interesting topic to be honest. I just wish this topic would be taken seriously in our own country.
