Why tf should a kid want to work? Why would you want a society to normalize a 14-year-old hustling and working after school? It's not authoritarian to protect children from parasitic businesses. Child-labor is illegal because at that stage a person has less emotional intelligence and rationality, they can more easily be taken advantage of and overworked, and won't understand their rights as a worker as well. You can't even sign a contract at 14 without a parent or guardian and you want them to be able to act at the whim of fast food managers?

Your argument is hardly one step away from the argument I see people trot out when defending child marriage.
