Apparently you have a far different breed of illegals than I had contact with where I lived in California. Those people were here to make money to send back to their families in Mexico and when the crops were finished they went back themselves.
They are very different, different from the migrant workers we had in the Yakima Valley around my relatives area. Up there we had a lot of settled Tejanos, who are US citizens and have lived here probably since the days of New Spain, and we had the occasional mojidor from Mexico (as they were called in those days.) The mojidors worked and sent money home, they tended to try to stay out of trouble, and they left when the crops were finished. The Tejanos owned a lot of the small businesses in the reservation towns and some worked in agriculture. What happened was that after WWII and again after the Korean War, many young men from the Yakima Valley were killed or decided to move away from the Valley, and a void was created where businesses were available for sale, and where commercial rentals were widely vacant and available and the Tejanos stayed and started businesses and quit following the crops.
The new breed seem to hold the law in contempt. It is like even the good ones gratuitously break laws and show contempt for our culture. Everything from tossing dirty disposable diapers in the parking lot at the supermarket to changing the oil in their cars and pouring it down the storm drain. It is beyond weird. When you ask them not to do these things, if they speak any English, they tell you that is how they did it in Mexico, or Guatemala, or wherever.
Complete contempt for US law, the US environment, and the American people.
So, no, I do not like them and I do not trust them. The contrast between them and the legal immigrants in our area is incredible; and many of our legal immigrants don't like them, either. They will talk about how bad conditions were back home - and then they will point out that these guys were crooks back home and they didn't gain honesty by crossing the border. One of our legal immigrant neighbors kept apologizing to the entire neighborhood for the behavior of one illegal family, and we had to tell him, all of us at one point or another, that he was no more responsible for their actions than the rest of us were for the Hells Angels, the Nortenos, the Mafia, the Triads, the Yakuza, etc. He and another father in the neighborhood separately told us that the thugs made them ashamed to be Latino, which is the real tragedy. No one should feel ashamed for the actions of others.
