Unfortunately the cause and effect you expect is not currently happening. The migration into this country has gotten worse in the last couple of years. The strategy being implemented is part of the problem. Also, the economic growth we have seen in the last four years also contributes to it. Mitt Romney's approach with self-deportation actually occurred when the economy was in shambles. So our economic success is a double-edge sword. Obama's administration quietly, relatively speaking, removed large numbers of people. If I recall, even one of his foreign family member's status of while here in the states was being questioned. In my opinion, there are several problems: 1. The risk-to-gain ratio is greatly in favor of those coming illegally. a) overwhelming numbers entering again that you cannot catch them all b) increased threat level in their home countries 2. The heightened threat of a real closure motivates those that may have waited to come, are encouraged to come before it is too late 3. Lack of US willing to invest in the infrastructure to have timely hearings and track of those with schedule hearings. This is also the case in our criminal judicial system, which they may become a part of. 4. Those that attempt to do it legally have incredibly wait times. During the wait, they may already assimilated and decide that our country is so great that they are then unwilling to leave. An incredible overhaul will be needed but then this issue would require an honest presidential and legislative approach. Unfortunately, I don't see that happening anytime soon by either party.
