In light of the recent discussions about Arizona's immigration enforcement, I'm just curious what you think is the reason so many people have immigrated to the US and why our legislators have failed to regulate the number here illegally. The government estimates 500,000 immigrants come into the country illegally each year.

According to a Pew Hispanic Center report, in 2005, 57% of illegal immigrants were from Mexico (6.570 million); 24% were from other Latin American countries, primarily from Central America (510,000 El Salvador, 430,000 Guatemala); 9% were from Asia; 6% were from Europe; and 4% were from the rest of the world.

Why do they come to America? Why not enforce the immigration laws?
