What do you think both federal and contract wildland firefighters do? They can be gone months at a time, and know this when they sign on. The benefit that draws them, of course, is the overtime that they make while away from home. Or what about private contractors who are working in Iraq or Saudi Arabia-not exactly garden spots for your average westerner (not to mention the risk of getting your head cut off with a dull knife)?
Pay enough and they will come.
I'm not talking about people who already have good jobs, or WANT them, and are willing to go where they need to go for them. I'm talking about the chronically unemployed. They are the ones who would be doing the lower wage, less skilled jobs that the Mexican and Central American immigrants are doing. They are obviously NOT interested in them, or they would already be doing them and we wouldn't need the addiditional labor provided by the immigrants.
