I am happy you are so independent. I am also very happy that I can stop at Wendy's and pick up a dinner for my family for $15. It is cheap and convenient. Illegals are hard workers and reliable. That is why so many businesses hire them. Businesses don't like to hire killers and thieves. Mexicans buy food and other products. So do their employers who would not be able to stay in business if they had to rely only on teenagers or the retired. The success of one business is dependent on, and influences, other businesses.
Lets take the janitorial services. A successful janitorial business might hire 50% latino. Lets shut that business down now. Half the legal employees now have no jobs. Those employees can no longer afford their first house, car, or child care. The chemical company that sold cleaning supplies has one less customer. The equipment company that sells mops has one less customer.
More importantly the businesses who relied on that company to clean the offices have to go with a more expensive competitor cleaning company and operating expenses eat into profits. Businesses that have low profit margins do not hire...and perhaps fire employees.
Now keep in mind that most cleaning, fast food, and farming employ at least some illegals. Immediately shutting down illegal immigration will hurt our economy more than 9-11.
