The column "Could riots such as in Paris occur elsewhere?" from Mexico's Ana Maria Salazar says that Mexico could have similar riots to those that occurred in France. But:

One important factor, however, has greatly helped reduce the risk of riots and violence in Mexico. There is an "escape valve" that the poor and discriminated in Europe do not have: the possibility of crossing illegally into the United States and getting a job. Authorities have calculated this "escape valve" has permitted more then 400,000 Mexicans to cross into the United States each year. Perhaps it is this factor alone that has stopped major uprisings in Mexico during the last couple of decades...

And, all America thanks the Mexican government for sending its people to us, thereby avoiding necessary reforms. But, what about all those potential rioters that Mexico has gifted us with?

As Paris burns, U.S. legislators will probably push for a bill that systematically seeks to close the "escape valve" by closing the U.S.-Mexico border. Ironically, they would be shutting down the very thing that could be preventing the riots that they fear.

Of course, if that were coming from a government official it would be a threat. As it is, it's just a warning.

We need to slowly back away from this issue by working to disincentivize illegal immigration and encouraging as many potential rioters as possible to go home.

Better the riots occur there than here. After all, our elected politicians are paid to prevent things like rioting, and perhaps they should do their jobs.
