If the US government had an immigration policy that satisfied America's employment needs it would make more sense to have every immigrant who works here apply for a work visa then a green card. As it stands now we give out something like 50,000 work permits a year to Mexicans, which is vastly below the demand of the economy. Nothing productive will happen when people form their opinions out of emotions over the percieved wrongs done to them by immigrants. It's simple economics: we need workers...they are workers...we need them. And finally, none of this would be necessary if America had used some of its vast economic and political power to improve the Mexican economy, reducing the 'push' of labor migration to el Norte. Instead we pass NAFTA, trying to turn Mexico into an export-processing zone that atrophies the rest of the country, especially the central and southern sections, where most of the immigrants come from.
