There are many Blacks in these Urban Communities who can't even get into the "Labors Union", but now the Firms who are doing the work are able to hire non-Union Illegals, but they never hired Black before.
By the way, an Illegal is one who is in violation of the Law. I don't use the "N" word to refer to anything, but I have never heard of it being used in the same way as a Law Violator. I think you are confused, and you might be trying to compare two entirely different things.
When a person cross the Border without authorization they are in violation of U.S. Law and subject to arrest and prosecution. Since the Law Violator has not jet been arrested, you would have to consider him/her a person who has crossed the Border illegally, or an illegal. Does that make sense? Maybe not, but i'll just have to move on.
