If I were not as advanced in age, I'd be tempted to undertake another of my several Entrepeneural ventures. A fleet of moderate sized boats could command some fairly good prices for transporting "Mexican invaders" around the stupid wall. There are two coast lines that would allow the "invaders' to simply go around the ends of the freakin' walls. Both U S coast lines are long enough to thwart the best efforts of the border patrol. The east and west coast of the US are both a lot longer than the southern border with Mexico. HA! We'd need to fence in the whole damned nation wouldn't we?
I am only half joking about this. Some of the commercial fisherman and shrimpers from Galveston, Corpus Christie, Port Arthur, Brownsville and other coastal areas could make a lot more money smuggling than fishing. So could the commercial fisherman along the San Diego, and other California coastal regions. And that is just the American side. Plenty of enterprising Mexican boat people could make a good living with the smuggling trade. The US Coast Guard would have to bolster their equipment and personnel capabilities even to make a dent in the problem. That would cost a lot of money Donald... Let me guess ,ever the profit maker, you could have Trump fleets of small boats that could cash in on the deal. The Trump boats would be more opulent and reserved for the more affluent illegals and therefore command better prices.
