People learn skills by performing them. As parents we teach children life skills by having them help do the chore that daily life requires. When I have yard, mechanic, or construction work my children help. They have since they were able. I learned those skills by doing the same when I was young.

By prohibiting capable teens from work, either by pricing them out or law, we are hobbling their ability to learn valuable work skills. As a result we end up with adults that are lacking simple work skills that would make their labor more valuable.
