My observation.
More often than not people who are here illegally...

Don't pay taxes.
Suck up taxpayer funded services like a hoover (schools, roads, parks, health care, food stamps, etc.)
Have a lot more than the 1.9 children that most planned communities expected.
Do not impress upon their children* the value of education. (*which they claim are americans so american has a vested interest in them as shown by the 48% drop out rate. )
Think 12 years old is an acceptable age of consent for a relations with a girl.
Drive drunk at a far greater ratio than the legal populace.
Have poor manners 'they don't seem to notice how customs change as they move up in class or start to adopt them.
Their children are rude to non hispanics (which is biting the hand that feeds them - because who is funding their above mentioned services)
Flaunt any number of laws and societal expectations because if they get caught breaking too many because they are undocumented can always run back across the border, change their name, come back and do it all over again

They are one of the worst societal investments that this country could ever make. Look at France and add ten years.

And Our senators are doing this why?
