I’d even the playing field. If free or sub-minimum wage is okay in some circumstances, it should be okay in all. If anything it is the usual culmination of unintended consequences: you slap on minimum wages for higher than new, unskilled employees are worth, supposedly to protect the poor, and you end up creating barriers so that upper-class kids have still more of a leg up than those who can’t afford to work absolutely free. My preferred route would be less regulation, not more, but right now we’ve got the usual, government-intruded upon system that is getting to be less and less fair.
I’m not exactly sure how you think you’d “even the playing field”. Any attempts to enforce “fairness” and evening the playing field pretty much always bring on more of those unintended consequences you were talking about.
