I've had to work the jobs that were available at the time, too. I don't see that as indicative of anything other than a good work ethic.
A good work ethic and having to work to feed your family are not always the same thing.
As for the experiences in Florida, let me tell you of one guy.
He lives ( finds a place to stay cheap) near Marco Island. He bikes his way every morning to Naples to hopefully get a chance to work. Notice, I said to hopefully get the CHANCE to work. The ride takes 2.5-3 hours each way, and he is there by 7-7:15. Then he works just as hard as any person at UPS. He did several jobs for us, some would be considered skilled, some not. He was very interested in doing a good job, and to please us with exceptional performance.
While I was spraying the pond (full body suit, mask, gloves etc) in the 95F+++black pond without any breeze, he volunteered to be the hose man. Something that no one else wanted to do. Never heard a complaint and was very easy to teach, even though he knew almost no english and we had to rely on another guy there to translate. He and I ended up working several 12-13 hour days in the heat.
For this he was paid $10 an hour, with another 2-3 an hour going to the Mexican mafia (read union officials) that saw to it they got to work. You didnt pay them, you didnt get any workers, or the workers that refused to ante up, did not get to work. So in Florida they have already learned well from the brothers at the AFLCIO?
As to the legal workers, they got paid more, but they actually probably took home less, because of taxes. When you make 15 bucks an hour, and you pay income taxes.........
As for the work ethic, I would have recommended the guy for any UPS position anywhere. Any job we asked him to do, he did so willingly and to the best of his abilities. I can say that he was not the norm though. I would love to put his name in the post, but it was really odd. The others you had to stay on to keep them working.
As for skilled vs unskilled, it depends on how you look at each job they were asked to do. Some of each at the very least.
d PS, we could never have gotten anyone to work for what I got paid. I did it to help out a friend in the business. All he paid me was a bit of gas money, motel room, and some meals. During the day and evening, I bought the guy that helped me his meals and drinks, as we needed drinks about every 10 minutes or so.
