Your statement is completely full of crap. We could function very well without them. Take a GOOD LONG LOOK at your income tax and property tax. How much money do we spend subsidizing them? How many illegal aliens are in prison? How much drug trafficking do they do? I look at the police reports daily in my local newspaper - every day the arrest reports list mexican names. I live over 1200 miles from the mexican border.
We can find US citizens who will garden, cook and housekeep. OUR citizens are part of our country. Illegal aliens are not. They have no intention of ever being part of us. Right after 9/11, hundreds of thousands of them high-tailed it back across the border.
I don't hate them. They are putting an enormous strain on our social system. I can cook, garden and housekeep for myself. I'll afford more expensive vegtables and fruit. Our social support system is for citizens only.
Excellent point, for if they had the intention, wouldn't they be "legal aliens" in the first place?
