I will give you the benefit of the doubt and assume you are kidding and simply wanted to hear me spell it out.
If I am a 'baker' at Hostess making X an hour, plus benefits, vacation, whatever it is, it is NOT in my interest for a flood of uncontrolled illegal immigration to come pouring in over time because, sooner or later, no matter how fair I think my compensation is, someone is gonna figure out how to sell a competing product or service cheaper and better than my company by utilizing all that illegal labor that is more than happy to do what I do but cheaper. A lot cheaper.
The second dumbest thing in the world is unions supporting Democrats because Democrats support illegal immigration which is a death sentence to unions.
The dumbest thing in the world is the GOP which can't make the simplest of arguments to voters. Of course, the GOP has it's own conflicts within it's ranks as many GOP'ers are all for illegal immigration so that they can win in the market with cheap labor and many GOP'ers are totally against illegal immigration.
Either way, uncontrolled immigration is really, really dumb if a nation wants to survive, let alone prosper. Both the D's and the R's have gleefully torn the fabric of this nation for political gain by allowing it and have distorted and transformed the nation in ways that are really bad for what we once knew as the United States of America and, even worse, what we once were is WHY people wanted to come here. They wanted to get away from the mess we are becoming.
