Interesting connection. Not sure the analogy works, but you certainly make your point clearly.
I have to agree with you: Illegal immigration drains the economy and the numbers are far higher than official estimates.
I also think this only one piece of a puzzle, or better put, plan, to undermine our country. There are other positions, philosophies, viewpoints and policies that very clearly harm America, and whether deliberate or the result of stupidity, the effect is pretty clear.
What bothers me even more than the illegal immigration though is the complete lack of awareness in the public of what's going on. The ignorance and puerility are stultifying.
