Wall-Mex

The Mexican government has consistently opposed the walls and fences erected by the US along the US-Mexico border. But, as my son, Gregory Weeks, has pointed out, Mexico is building a wall along its southern border with Guatemala in order to keep out "contraband" and, of course, illegal immigrants. Trying to fence off the US from Mexico has, by all available evidence, done nothing to deter undocumented immigrants from entering the country. Rather, it encourages them to stay once here, since the cost of going back and forth is now higher than it used to be. There is no reason to believe that Mexico's experience will be any different.
