Actually cheap labor did build this country or a portion of it. That's why we had a Civil War.
Notice a trend here: Indentured servitude, Slavery, Chinese working the railways, immigrants from Europe, illegal immigrants from Latin countries.
love your commentary as usual park...but the UaSsA dont need cheap illegal labor, infrastructure is 1st world and public school system is a failure so it produces a blue collar working force in-house. 21st century is a different vs 300 yrs ago n chicken george and the chinatown kid.
your leaders f##ked up opening the boarders for a free-for-all. mexicans are here to replace AAs. but you cant succeed with a nationalistic group vs a group that knows no other home. ignorance and racism still rule the constitution.
now...whitey scared cause 1st gene mexicans have absolutely no interest in learning the language, done figure out the system of welfare and food stamps is better than 5$ USD per week n the slums, and some other things too long to write.
and lastly...the bad apples in mexican are starting to migrate. why stay in mexican and deal with cartels when you can rob, steal and BS in america? get busted and get 3 meals, a bed, gym, game room and the comforts of america prison life.
depending the security level of a prison...it's more comfortable in states vs being in a cell with 20 mofos sheepoing on dirt flrs and having the daily bread and unseasoned beans.
to the other poster a while back....no latinos are going to be shooting blks in the streets cause most of us are blk and assimiliate. texas and everything west of it will be interesting in 25 yrs. from my experience where the hell
whites are going to move...since there is an exodus from neighborhoods now?
LIVE WITH IT! 
YES...I AM.
