Does the amount of pocket money?

Yes I give my teens $5 dollars a week for the chores they do. I wouldn't personally have a problem with $20 a week as long as he is buying everything himself -clothes, movie tickets, fast food - anything that's not a necessity etc. I'm going to side with your husband on an after school job - it'll take away his study time and time with friends sure he'll have money to buy things. He doesn't need things. Maybe during the summer he doesn't have any bills and should be able to save up a lot.
