Well that's probably part of the problem. You have to live within commute range of the work to do it, and people don't want to live in small towns or Central Valley CA unless they're in the respected local landowner class.
I know there are people who do part-time work in oil fields or fishing ships, so that's always possible if you want to move to North Dakota or Alaska temporarily.
I don't know about the rest of the nation, but in the American Southwest, there's a distinct socio-economic class of "migrant farmworker" with a long tradition. And it's a Hispanic cultural tradition.
There would be basically zero chance of anyone in my urban high school, or circle of friends, to turn around and say "I'm going to be a migrant farmworker when I graduate!" and it's unclear whether any non-Latino could even achieve such a career. GP indicated that urban/suburban living wouldn't be possible. You'd certainly need to move around, and you'd be an outcast if you didn't speak Spanish, if you weren't nominally Catholic, or celebrate holidays like a Hispanic. Your children would come to learn Spanish and cultural customs, but they'd still be outcast because of racism. You'd have a weird relationship with the overseers, because they'd be more like you, so neither side would really accept you.
(Sub)urban White kids are usually groomed to go to college and get a white-collar or office job, and the dropouts do some kind of tech vocational path, or end up doing clerking minimum-wage to get by. So you have a spectrum of white/blue collar, but there's no path to "migrant farmworker" or other sort of laborer, because my people Just Don't Do That. It's unthinkable.
Even agrarian Native American communities have a huge problem with "brain drain" there, because the opportunities on the Reservation are zilch, unless you want to work at a casino? So young Natives dream of leaving at the first chance, going into the city, and assimilating, losing their culture, because it's a survival thing. Their agriculture isn't sustainable, no matter how you slice it--what are they going to do, hire from outside?
Since the 80s we've had White people who said that migrants come to steal our jobs. Or they say they're taking jobs no American wants. But realistically, even if American wanted those jobs at those wages, they couldn't have them, because of the ethnic hegemony in certain industries.
I see. Yeah, that's tricky. It's less of "I don't want to" moreso than "I literally* cannot move". I'm paying off a house and moving to another state to pay rent on top of that mortgage ruins the point. For 200k, sure. But I know that's not realistic even if I was the best farmhand.
*Okay, I can "literally" talk with family about selling the home. But I do just need some steady work during the downtimes. I'm not at a point where I feel I want to uproot my entire lifestyle, career, and livlihood just to do blue collar work.
