Maybe the unions are quietly working to stop amnesty behind the scenes. The unions can say one thing in public and say something different to thier stooges in congress privately. The rank and file union members know that illegals drive down wages. The congressional black caucasians also know that illegals hurt Holder’s peoples’ wages. 0bama and the democrats could have rammed amnesty through congress in 2009 but they chose not to do it.
Meat packing is a perfect example. In the 80's those jobs could pay as high as $18/hr. Now it is done by illegal labor for <$10/hr.
In Vegas a large portion of the hotel staff is illegal, but SEIU doesn't care about Americans looking for jobs or union members whose wages are suppressed. All they care about is getting the illegals to sign up for the union.
