Again ;the problem needed resolution in the 1980s... long before the bombs. Here in the east I have been screening employees for years and have hired MANY legal immigrants from at least a dozen different countries ;including many Mexicans an other hispanics who took the effort ,and respect for their new countries laws ,to get the required documentation for legal residency. So no I don't think it's a good idea. My guys get paid fair market ;and lawful rates for their work . Do those guys working out west ? No . The same people who complain about slave wages overseas turn a blind eye when it happens right under their nose so they can eat cheap arugula .
