Immigration Nation

I recently got an email with this comment:

Calling an illegal alien an undocumented worker is like calling a crack dealer an unlicensed pharmacist.

This nation was founded by people who were immigrants. Unless you are pure American Indian, your parents/grandparents/ancestors were immigrants. I highly doubt that illegal working aliens are putting a financial strain on this country greater than the value of the services they provide. If somebody can show me a study that determines their burden versus their benefit on the taxpayers of this great nation, then I'll listen more closely to comments like this one.

The measure of how great a country is can be determined by the number of people trying to get into it, minus the number trying to leave.
