Of course there are more illegal in US than anywhere else. The local population refuse to work in the field and "low" paying job.
Only 4% of illegal aliens in the US actually work in the agricultural field. Go to any Mcdonalds and they are now staffed by illegal aliens, 10 years ago this would have been an American teenager working that job. Coincidentally jobless youth is at an all-time high...
20% are employed in construction. Construction isn't exactly a low-paying job for a skilled contractor and many Americans without degrees are perfectly willing to do that work but have to now compete against 3rd world wages in a 1st world nation.

Shut up - you're an American citizen and your concerns are irrelevant (at best, secondary) to this President. Today, the interest of American citizens come last after all other considerations, especially if you don't vote the right way. Do as you're told, or we'll get NSA/HomelandSecurity/IRS/FBI/etc. on your ass. Racist.
(sarc, btw... sort of)
