We are not at threat from Mexicans any more than our own government.

Where the US Government is at fault for stripping the US citizens of their rights, liberties, and freedoms on a daily basis, I would hardly say that
is not a threat.

The Tucson sector Border Patrol union local 2544 on the number of illegal aliens in our nation: "There are currently 15 to 20 million illegal
aliens in this country by many estimates, but the real numbers could be much higher and the numbers increase every day because our borders are not
secure.

20 million illegals in our country, and that's not a problem?

The illegal alien population is currently 70 percent Mexican, with 30 percent coming from other countries.

That's 14 million alone from Mexico. That's not a problem?
There are laws for naturalization. If you don't follow those laws, you're (you generalized) breaking them, thus making yourself a criminal from the
get go. If a criminal has no right to be here in the US, then they need to be sent back, immediately.
You are right, however, we do need labor here in the US.
The number of unemployed persons (7.0 million) and the unemployment rate (4.6 percent) were about unchanged in January 2007 compared with December
2006.

Looks to me, there's plenty of work to go around for American citizens.
