It didn't make me "better" but from talking to people I went to college with (that didn't get jobs early), I'd definitely say I was more prepared for the workforce.

Also having money was dope and my fast food job was fun. I still enjoyed my life and summer outside of work, even more so because I could afford to do and get shit that my parents might not have been able to give me. It's not an all or nothing deal it's just a different life experience. I think it would be infantilizing to take the choice away from teenagers, though it is important to regulate it as shitty people will take advantage of it.
