If its a global labor market, where is the pressure on, say, France or Spain to receive these workers?
And, actually, it would serve Europeans to import Latin American immigrants rather than Moroccans or Algerians. The fact that their immigration policies do not tilt in favor Latin America is a huge mistake on their part.
Beyond that, if people want the services of Mexican workers, then the Mexican government should work on eliminating those factors that make it difficult for companies to locate their operations in Mexico. Specifically, the security issue. Given the choice between a country that is near its markets but its execs face kidnap and its truckers being hijacked, like Mexico, versus a country that is far from its markets, but your execs and suppliers are secure, like China or Thailand or Korea or Taiwan, companies are going to choose security.
Mexico is a natural, it is the most obvious place for companies to base their operations, and at one time there was a big move to base factories there. It hit a snag, though, and that snag is called “security”. Solve that, and Mexico will have labor shortages, and they’ll be forced to import workers rather than pushing them out the door by the millions.
Already happening. Go to any construction site in Italy or Spain these days and you will see Ecuadorians.
