There are many seriously dangerous effects from illegal immigration that range from health issues to criminal issues to the watering down of labor laws.  Why do illegals want to destroy unions and labor laws that will only hurt them if they do become citizens?  It seems very poorly thought out to me.

I also don't understand why people in Latin America place all the blame for bad conditions on other governments.  Is is not true that if their own governments were responsible toward their own citizens then Latinos would not be fleeing their countries in droves?  They don't have any problem getting in the face of foreign governments of countries they want to enter, but I don't read articles about these same people standing up to their own governments and demanding more livable conditions.  In Mexico, even the president threatens the U. S. government to let Mexicans freely enter, but he doesn't say, well, I guess we really need to change some things here so people will want to live here.

Then, when Hispanics arrive in the United States they have an active dislike for Americans whom they've been led to believe are lazy and worthless and have stolen their land.  They retain loyalty to their home country--especially Mexico--and criticize the United States as a monstrous society.

Illegal immigrants raising concerns in Latin America

LIMA -- Efforts to stem illegal immigrants from neighboring countries are increasing in parts of Latin America because of concerns, similar to those in the United States, that they drive down salaries and bring crime and violence with them.

[...]

Driving the changes are concerns echoed in the current U.S. immigration debate: that undocumented workers take jobs from locals, raise the crime rate and drain tax dollars through their use of public school and health systems.

In the same vein, business groups in the region have been opposing new laws that might limit uneducated, low-cost laborers from migrating to countries that need them -- just as in the United States.

[...]

Undocumented Colombians in Venezuela have prompted concern there, said Raquel Alvarez, an immigration specialist at the University of the Andes in San Cristobal, on the Colombian-Venezuelan border.

''There's little anxiety that Colombians are taking the jobs of Venezuelans. They take jobs in sectors where there aren't enough Venezuelans, such as textiles or on farms,'' Alvarez said by telephone. ``The concern is that violent elements are crossing into Venezuela to commit killings and kidnappings.''

Argentina plans crackdown on illegal immigrants

BUENOS AIRES, Argentina (Reuters) --

The Argentine government on Monday defended a new bill to crack down on illegal immigration from  accusations that it was a dangerous response to rising crime and high unemployment in an election year.

"Every country in the world tries to control illegal immigration," Interior Minister Carlos Corach told reporters.

"I don't see why stopping people from entering the country illegally should be considered xenophobic."

"The aim is to control illegal immigration, not against our Latin American brothers who come here legally to work," he said.
