I had a similar experience when had a more than $100K renovation of my house--new kitchen, bathrooms, electrical rehab, etc. The contractor sub-contracted for much of the work that was done by people from Central America. These used to be good paying jobs for Americans.
I have interviewed blacks who were displaced by immigrants legal and illegal. One black veteran said he was making more 20 years ago as a bricklayer/stonemason than he was now. He said he had a hard time communicating with the mostly Hispanic workforce. He felt like the odd man out because he couldn't speak Spanish.
Based on polling my grassroots immigration group has done, we found that blacks were even stronger than whites when it came to immigration and illegal aliens. They want reduced legal immigration and removal of the illegal aliens. The numbers favoring that were 88%.
Everyone is chasing LOW COST. All professions are taking a hit not just blue color workers. Many people go to Mexico to get their Teeth fixed<> Many Engineering cos. outsource to Low Cost Centers around the world
Many IT / Software professionals face stiff competition from LOW cost centers
Simply the way of the world, some years back it was the Automobile, going back further it was the Steam Engine revolution
If you had to put a number on how many Hispancis will go for us and how many blacks will come our way what would it be?
