Operation Wetback( not trying to offend that is what is was called) worked too but that doesn’t mean that it would work today. Even the name would not work. The Bracero Program spawned Operation W. Our Northern and Southern boarders are in a sad state worse then during the Bracero Program since we were in World War 2 and needed the labor that is why FDR commissioned the program. I submit to you labor is not a problem the availability of jobs is. They had control with a max of 444,000 in 1957. Now the states and for that matter the country cannot handle the extra influx of people. The government has not been able to control anything and do you actually trust the feds to conduct this mass immigration with out corruption? So what happens when the participants fade into illegal activity or worse commit terrorist acts?
There is some ranchers who are using a similar program today, several months ago Fox did one of their all day stories about how they came in with green cards allocated to certain jobs, the ranchers paid them a fair wage for their work and then made sure they returned to their home countries when the work was over, I think this is the best way to solve this because their families don’t come with them and they know they can leave and come back when there is more work...
