Holy smokes, that would be an interesting way to fund government... I like the thought exercise! This whole mess has been a nasty festering sore for decades. The right never wanted to solve it due to the cheap labor for big business. The left never wanted to solve it due to votes. Whether it's exponential or not, it's a very real problem, and no country in the world deals with it to the extent we do. No one really knows how many illegals we have. Estimates range from a low of 10Million to a high of up to 40Million. By various middle guesses, supposedly 20 Million illegals in this country. So between 5 and 10% of our entire population is here illegally. Anyone who doesn't see that as a problem that we should solve has an agenda of one sort or another. I heard today on the news that illegal immigration is down to an all-time low. We now only have 400,000 illegals entering the country per year. Think of how many people that actually is. That's a truly incredible number of folks continuing to enter that we don't know who they are, what they're here for, where they came from, etc. Sure, I'm willing to bet that 99% of them are here to work and better their lives. But the rest are not. And 100% of them have a demonstrated lack of respect for the laws of the United States. I'm growing increasingly comfortable with the ideas of 1) leaving the government (partially) shutdown, and 2) supporting Trump exercising emergency action to deal with this crisis. It has been a defining issue of our time, and I suspect there won't be anyone along any time soon after Trump who is willing to deal with it directly.
