This situation has actually been going on since the 1930's. There's an old Woody Guthrie song about a plane crash involving Mexican migrant workers
where all aboard were killed; the song is called "Deportees."
There were a number of songs about this in the 1940's; the agriculture business was too hard (manual labor), too hot, too dangerous for most
Americans. As factory jobs opened up, nobody but the immigrants and the non-Whites (who couldn't get decent jobs) would chop cotton or work in the
insecticide-sprayed fields.
Caesar Chavez was a man who led the fight for rights and better treatment for the migrant workers (he was the grandson of slaves and many of these
workers were treated little better than slaves):

So, yes, we see lots of immigrants taking over these jobs.
It's also a problem with our society. I work part-time at the university in the computer lab. I'm one of only three American-born citizens in the
group of 50 workers. This is a low-level techie job, but the other Americans who take these jobs generally don't want to work the hours (only 20
hours) and usually quit. We're not talking a hard job; just a fairly low paying one with a lot of perks (like free access to the computers and a job
where you can surf the internet and nobody shrieks.) And the boss is really REALLY good to us. Picky, but good.
But Americans don't want these computer lab monitor jobs. The foreign-born students get a huge break on their tuition if they take these jobs, and
they line ujp for this.
If there were a lot of American-born kids lining up for these jobs, believe me there wouldn't be any migrant laborers. There's a demand for these
workers and the bosses will fill them with anything that can walk and breathe and will do the job and won't get in his face.
And that, friends, is the worker who comes from Mexico, Guatemala, Nicaragua, etc, etc. If you don't want the situation to continue, then start
helping people who need jobs here in the country to go out and get these jobs.
TrueLies, yes, Mexicans do go on vacation -- however, remember that there's a HUGE economic gap between the "average citizen" and the wealthy one
who can afford the vacations.
