Child labor laws weren't meant to protect someone like you, they're meant to stop folks from sending their kids to work to pay their rent/mortgage/power/water. Kids should know that paying their parents bills is not ideal, and child labor laws are how we protect them. Without revealing too much about myself, my dad was one of [large number] of children, and they absolutely used those kids for labor at the family farm and were worse off for it. They grew up in poverty (on top of the physical abuse). Basically, these laws aren't supposed to stop young Timmy from buying a [insert gadget here], they're to stop Mom from pulling him out of school for an extra shift because she overdrew her bank account.
There's no way that kid is 13, by the way. Far too young for working the register at Culver's. At least they don't have him at the deep fryer. If the other comment I see in this thread is to be believed (the one that says this is a Manager's child and school was closed), it's probably not as nefarious as it seems. Republican states have been in the news fighting against child labor laws though, people are rightly outraged about that.
