Cmv: Building the wall will worsen economic conditions in Mexico leading to an influx of illegal immigrants, not a reduction of them.

Fleeing one's homeland is not a decision made lightly. Most people immigrate out of necessity. Building a wall on the southern border of the US and making Mexico pay for it via sanctions and tariffs will weaken an already bad Mexican economy. Which in turn will lead to an increase in illegal immigration as more people than before are now looking for better ways to provide for themselves and their families. Instead of building a wall to keep increasingly desperate people out of our country, we should lend our support in helping them rebuild their economy instead of having a nationalistic "us and only us" view.

Not necessarily 

I don't have fact to help out but the wall impacts maybe half a million to 1 million people. These folks are already in desperate situation in Mexico or Central America for one reason or another. It's not your 1990s immigration wave.  These people will then settle back in Mexico or try by other means: currently most of them are deported back, so not a very different scenario.

On the other hand - not part of your CMV-Nafta would have a larger economic impact than the wall. 

Breaking up Nafta or a border adjustment would easily impact 40-50% of the Mexican population negatively: more 50 million people could be looking at a drastic decrease of income within 2-3 years. That would be a crisis and drive people down the fences.
