As Americans have been doing for decades and proud of it!!
I drove a taxi for years and visitors to Hampton Roads preferred Yellow Cab (they refused to hire illegals) because the drivers could actually speak and understand English. My late wife worked several years as a landscaper. Customers liked having people who spoke English. Her boss (owned the company) refused to hire illegals.
If we deported all illegal immigrants in 2-3 years, we would rapidly fall into a severe economic recession because of major labor shortages in construction, hotels, agriculture, and restaurants. Deportation of all those people is out of the question economically. But I do believe it's time to close down the border and stop letting more illegal immigrants into the country. Those who are already here should be required to register for a guest worker program.
The economic analysis that Phyllis quotes is also faulty because in a correct analysis you have to count all the additional taxes paid by the owners and other workers in all the industries supported by illegal immigrant labor: for example, owners of construction companies make more income because of abundant illegal immigrant labor and so do all kinds of workers in construction engineering, real estate sales, building subcontractors, and all kinds of building material supply companies that make lumber, pipes, wiring, drywall, concrete, electrical fixtures, HVAC equipment, etc. The analysis she quotes is a faulty analysis that doesn't look at two cases for the entire US economy. A correct economic analysis looks at the entire economy, not just the taxes paid by illegals and the benefits they recieve. There are also future benefits in the education of illegal immigrant children that are not counted here. Mexicans who are educated here do assimilate into our culture. We had some Mexican immigrants who did yard work for my parents and while the Mexican parents didn't speak English too well (but not too badly), their 11 year-old daughter was competely fluent in English and she served as their translator.
