That's an admirable goal, and get him to participate in it. He's too young to work but there are always yards to rake and lawns to cut, washing cars, w/e to help with expenses. Put the money in an account for him so that his father can't get a hold of it and that way he'll feel like he's helping himself instead of just waiting to get rescued. I don't know the whole situation and maybe I'm wrong but it might make a difference, help his brother feel like he's in more control of his own life.
