i can see barring certain jobs from children but honestly there are a lot of jobs where no need for an age restriction. something like working as a cashier a kid is either mature enough or not...kinda just natural selection and alsoup to the owner what age is reasonable for the job they hiring for and how much mentoring they are up for.

but i know thats so hard to do in reality, so hard to not over protect children from a community's standpoint, let alone a politicians standpoint.
