"Wanting a better life however doesn't give them the right to break our laws and enter this country illegally"
Why don't you tell that to the pilgrims and all of the other settlers that came onto Native American land (which did include those Mexican "immigrants") and then stole that land which didn't belong to you destroyed it set up an illegal government and now are whining and complaining about some people who probably had ancestors who were the people you drove from their land, coming back to their land and working really really hard for really really shitty pay. The answer here is too either stop whining and let them back onto their land or just get up and leave America and take your damn government with you!

OK, and while we're at it we'll figure out which tribe of natives killed off the other tribe who originally held the same land, and which one before that, so we can make sure it all goes back to the original owner, which was probably a badger.
