Is making your child work during college counter-productive?

I’m currently working 20+ hours a week in the admissions office at my University. I need the money for groceries and to help pay loans. Sure I’m probably learning some life skills (Which I probably learned through high school jobs as well) but if I didn’t have to work, I wouldn’t. I probably sleep 5-7 hours a night, and don’t have time for anything besides homework on weeknights.
