I don't have a child but I think it might be better to sit him down and give him a lesson on economics. Be open with him regarding your finances; show him your checkbook and you pay slips and explain how the math works and that inasmuch as you would love to buy him those things he likes, it's financially impossible at the moment. Maybe even give him the responsibility to manage your checkbook. He's 15! He needs to learn it sooner rather than later. And a part time job ain't such a bad idea either. If he can make his own way, he might appreciate it the struggle to make ends meet and everyone will be a little happier at the end of the day. Good luck with this! I hope it works out.
