Being that I live in Arizona, I am in full support of a wall being built. However; this wall will really only help alleviate burdens from illegal immigrants in the southwestern states. At the same time, those who live elsewhere in the United States don't share the same issues that we do, and unfortunately most of them center around the children brought across the border. Maricopa County alone has now 18,000 kids in foster care (2nd position to Texas) and our schools do not receive proper funding to educate these kids. We don't know if they ever received a formal education, thus they take the standardized tests and fail ... which only leads the government to believe that our teachers are not doing their best. Arizona ranks among the worst states in regards to education (thank you ESOL students.) So ... funding is cut there. It is an issue that is severely out of control at the moment, and there is not an answer that will rectify all the problems.
The cartel still digs tunnels and uses drones now to drop drugs across the border ... but alleviating issues of stopping those "seeking for a better life" will enable the border control to put more manpower in our other problems.
It's very easy to sit back and make fun of the southern states who support this, but the domino effect of costly ramifications is something you won't see since it is a "state" issue.
