It’s my personal opinion, and my opinion isn’t worth squat, but the only logical explanation of why the U.S. Government hasn’t sealed our border with Mexico and deported every illegal alien within this country is that the drug traffickers have done here what they’ve done in every country between here and the Andean Ridge, they’ve simply bought elections and put their people into key positions within our government. To think otherwise is to be naïve beyond belief.

That may be some of the reason. IMO the main reasons, though, are (a) the Cheap Labor express and (b) more reliable Democrat serfs.

That's the corollary, or perhaps even the ancillary. The primary is to keep the largest non-participating group in labor in the history of the US down.
