It's unfortunate that Americans are reduced to talking about the construction of a wall. Unfortunately our lawmakers have did little over the years to really address the problem,  yes P-R-O-B-L-E-M of illegal immigration.
If we would stop rewarding people for sneaking into OUR country and driving our blue collar wages down, and instead go after anti-American employers who hire these people, and at the same time deport these people, we wouldn't have to talk about walls.
