How come he is not working? The age minimum is 14 years old, unless your state has a different age requirement?
The teenagers in my neighborhood usually get jobs local and with their friends, and go in together on same shifts. It becomes social, funn and they have their own spending money for the summer.
My mother had 4 kids, I was the oldest, and I started working as camp counselor at the age of 12, and bought my own clothes for school if I wanted something that was the fad etc. I learned the value of money very young.
Funny even now, if its a luxury item, even if I have the money, I always think twice about buying it.
