You used to could make a decent living as a framer, a roofer, ceramic tile installer, painter, etc. in this country and plenty of folks would welcome such work were it available and paid a living wage. I don't know if tomato pickers ever made a decent income but it's honest work and they should be paid well. The thing overlooked in all this is that just because a job is hot and sweaty doesn't mean it's unskilled labor and and anybody can do it. You can't readily go from a lifestyle that includes litte sustained exertion into putting in eight hours as a harvest laborer. I remember back in the day, I made a good summer income stacking hay on trucks and then restacking it in the barns. Paid by the bale and pretty greedy, I made three times as much per hour as friends working in grocery stores or other available jobs for kids 16-18. A few friends tried working with me. Not many liked it enough to keep doing it even for the money. A lot of kids that looked muscular and fit weren't up to working in the heat all day.
