The Mexicans are coming.
They're coming to harvest the produce you eat.
They're coming to work your gardens.
They're coming to nanny your kids.
They're coming to...do whatever the hell other jobs Mexicans do in the U.S.
They're coming because, despite what you tell yourself, you want them to come.
You want them to come, because none of you who are going to bother to read this ever had any intention of spending your lives in an orchard or in a field, 12 - 14 hours or more a day, five or six or seven days a week in the blazing sun breaking your back to harvest produce. Because you never had any intention of spending your days planting flowers and pulling weeds and spreading fertilizer and changing mulch in someone's garden. Because you never had a dream of taking care of someone else's kids for a living while their parents are gone. Because you never had any intention of doing the myriad other menial jobs you now think are being taken from you.
You went to college, instead. Or got any number and types of technical certifications. Or joined the military. Or started your own business. Or got a job that requires a higher skill level and/or a linguistic and cultural fluency that an immigrant doesn't have. You wrote off those jobs as beneath you, and assumed that there's a whole bunch of 'other' Americans (not you, or most anyone you know, of course...but out there, in some abstract sense) clamoring for them.
The thing is, though, it seems that those Americans we think of as 'others' consider Americans they don't know as 'others,' as well. And they all seem to think that those 'others' want those jobs and would be doing them if it weren't for the sneaky immigrants.
Oddly enough, I don't recall ever reading any stories about born and bred Americans, Minutemen included, lining up outside of farms and the like looking for that sort of work, despite the ~5% unemployment the U.S. has today. Nor do I recall reading any such instances years back when unemployment was much higher (bear in mind, I'm talking about the past 30 years or so. No need to bring the Great Depression to my attention). People were still eating in the recession, and crops were still being grown and harvested, so I can't imagine that those jobs simply didn't exist for a few years...
"A-HA! Because the Mexicans drive down the wages for those jobs!"
Indeed, they do. Because you want them to. Because just as you won't work those jobs for those wages, the employers won't pay you the wages that might make those jobs seem more enticing. Because if they did, you, and the vast majority of other Americans, wouldn't buy those goods at the resulting price. Not when there's always imports competing with them. And you and most others couldn't afford those personal and home services if they were provided by born and bred Americans.
Of course, low wages to us are several times what they'd make doing the same thing back home. Crowded, spartan living conditions to us are probably almost luxurious to them. A generally rotten, unacceptable deal to us must be a pretty sweet deal indeed to them, or they wouldn't be coming in droves like they are.
And make no mistake, they will continue to come as long as it is profitable for them to do so. They come because, whether you like it or not, there's a demand for them. They come because of the basic law of supply and demand. They come because our system works. Short of digging WWI-style trenches along the border, complete with minefields and machine guns nests and pre-sighted artillery and orders to shoot border jumpers on sight (none of which is ever going to happen, you and I all know), they will come. Anything we do short of the extreme, politically impossible and morally unacceptable, will be building a razor wire fence to stop a tsunami. A useless waste of time and effort on one hand, and an embarrassing display of impotence on the other.
So, instead of making fools of ourselves trying to prevent the inevitable, why don't we concentrate our energies on making the inevitable work out better for us?
Our immigration system can't process people at the rate they're coming in? Expand it, and/or streamline the visa process. More people want in than the quotas allow? Raise the quotas. If there aren't jobs, they won't come.
They're overwhelming our welfare state? Trim the welfare benefits (yes, I know, easier said than done).
They don't speak English, aren't familiar with the cultural norms? Teach them. Get an ESL job in Cali or Texas. Or volunteer. Or freelance.
Find a bunch of them and get a business loan or investment and open a genuine, gourmet Mexican restaurant, or simple diner in your area. Organize them to teach private Spanish lessons. Start a landscaping firm and use their cheap labor. What? Someone's already doing that in your neighborhood? Do it faster, better, cheaper.
Be a capitalist and entrepreneur and seek out and exploit opportunity.
Anything. Just stop lamenting the rising and setting of the sun.
