Usually, people move as individuals, or individual families.
I don't know who sent out the e-mail to Mexico about Mexicans moving in massive droves to a town near me, but they had a massive influx of Hispanic families to a relatively small town.
Keep in mind, this is not anywhere near the Mexican border. This is in rural PA.
I called the FTL show about this, by the way. 5 years ago. Ian went "Oh NOoo!! Did the poor little townspeople lose their fucking minds!!?" Or, something like that.
Since then, property values dropped like a rock. Crime went through the roof. Property taxes reassessed - fucking TRIPLED dudes... The police force hired dozens of cops, as did neighboring communities, and the courts are completely fucking swamped with tons of half-assed busts. Hispanics are "muleing" tons of dope through what is now known as the "Golden Triangle" between NYC, Philly, Reading, Allentown, and Cleveland, Ohio.
The county was embroiled in what is nationally known as the "Cash For Kids" scandal, where two juvenile Judges got busted for taking bribes to pump up the Juvy system with kids, which in turn forced the County to outsource Juvy housing and ultimately build a new Juvenile facility.
Because a lot of the Hispanic families were somewhat transient, they couldn't prove adequate housing or schooling records, which resulted in additional problems, the kids couldn't be released as easily as they would to a "stable" family.
More hiring of needless community and social workers, foster housing, and all the rigamorole.
Guess who pays for all that? Its a large county, and a long-term problem... remember, I said this has been festering for well over five years now. Welfare housing maxed, adult inmates stuffed into County lockup like sardines (I did time there), increased patrols, additional cops - and lots of 'em, a brand new Juvy facility, all the necessary staff. Hundreds of full-time jobs, times 30-40 grand a year.
Over ten years, we're probably talking a hundred million dollars. Just in one county.
And you know who's really getting the snake-eye? The legal Mexicans. Because nobody knows who's who. If I was a Hispanic who'd been here for some years -- all on the up-and-up -- I'd be fucking pissed off. And I heard exactly that from a couple Hispanic folks I knew, they're embarrassed, and fearful of their safety, and the safety of their kids who are reaching driving age.
Think about it... the legal Hispanics are pissed, and some want to leave, because their "own kind" is fucking the community up.
