No. It's pretty much always a result of another system failing. We're not talking about a kid helping out in their mom and pop's shop. We're talking about kids working in meat plants because it's cheap labor.
If they have to work to help out with money, then our system has failed in providing an adequate environment for a kid to grow up.
If a child wants to learn a craft or pick up specific skills, that should not be done in a work environment that can put them in danger. Again, that's another failure of the system.
Most of us already have to basically work until death since they can't ever properly retire, so I see zero benefits in forcing humans that are still developing into that reality even sooner.
