The song "Somo más americanos" form Tigres del Norte is quite beautiful because it expresses an unconformity to the United States of America of how they discriminate Mexicans when they cross the boarder to the states like New Mexico, California. The song expresses this unconformity by saying that the mexicans where first settlers of those territories thant the Americans.
Nevertheless, I think this point of view is pretty precarious due to that mexican people are still basing there lifes and beliefs in a culture that emerged almost two centuries ago and they are not realizing that from that time to now, there is progress and change.
The Americans shoud have merit for owning those territories well that clearly shows that they were superior than the native mexican indians so I don't know why the mexicans are still crying about those aspects if loosing great part of land was their fault for being inferior and maybe not having the capacitys that Americans had in those times.
Good luck next time Mexico. ;)
