what created the symptom. that's easy. demand for cheap labor to fill needed job positions in food, service, construction, sanitary and agricultural sectors of the economy. since legal workers are not fighting each other to fill these positions, then the illegal workers are dying, literally, sometimes to fill those slots. when you are working for $2-3 dollars a day in your country, at $5.25/hr for working a minimum wage job here in the USA is worth it all. even if it involves doing an unpleasant, dangerous or unwanted job...it does not take a genius to figure this out..YMMV.
Now, there's problems alright clearly evident here in the USA...
# 1: what are you going to do about the 12 million, depending on whose figures you wish to employ, illegal immigrants already here entrenched in the economy?
#2: what are you going to do about the USA's porous borders (North and South), cause it's not about race...right!, which allowed the above 12 million people to intrude into the country? Border Patrol and all...

roblems..we got problems. what are we going to do about it? we have only begun to see how looking simplistically at complex ( social, cultural, political and economic) issues will get you nowhere fast. the results speak louder than words. Don't tell me jack, show me!
