More likely that a marxist government will come to power as in Venezuela
In my opinion, this is very near the top of the Administration's reasons for not strengthening border security--perhaps a secret agreement with the Mexican government to keep what you said above from happening. If those peasants in Mexico suddenly have nowhere else to go, they'll revolt, many of them wearing Che Guevera t-shirts, btw. If fear of a Marxist Mexican govt.is the case, then I'll be very disappointed in our government's falta de huevos.
