Illegal immigration is destroying our country's entitlements, resources, and public services. It encourages under the table jobs and using identity theft for working, which are both illegal. Illegal immigration depletes hospital ER's, increases crime due to street gangs, reinforces drug and human smugglers, allows the abuse by illegals of the anchor baby citizenship, and encourages disrespect for America's government and laws. You have illegal immigrants demonstrating in the streets of California and Arizona stating that these states are really the property of Mexico and because of that they are already citizens because of their Mexican heritage. The current situation encourages law breaking and disrespect for the country that right now is giving them free health care at hospital ER's.
