I really hate to say this, but...we will need those folks to fill those jobs . How many young people today do you think will go pick crops, clean houses, etc.?
They should be legal and vetted. And perhaps with temporary work visas like were used in WWII.
It would do young people today a world of good to go out and pick fruit or harvest food. That way, they'd know where it come from, but they might get some common sense instilled in them and maybe even a little work ethic.
In the crews, leaders will arise, not through bullying or whose daddy has the most money, but through raw ability to get people to do things and work together. A sense of teamwork could be developed, and perhaps some good-natured competition.
All in all, it is a fine opportunity for personal growth not presented by making snarky comments to an anonymous person behind a screen.
It might get them all in better physical shape, too.
