What the hell is wrong with your parents? If that was me, my dad would have whooped my ass. I skipped a day of school once because the bus left me and I didn't feel like walking. When he found out, I got yelled at for like an hour minutes, I was 17 at the point, so we were past ass whoopings since I very rarely would pull something like this off and I never did after that. Just sounds like you parents don't give a shit about him apparently or just terrible parents. Any sensible and responsible parent would have taken immediate drastic action after the initial $500. Start by taking all his games away and tell him to get his shit together or you will sell them/give them away. I'm assuming he will rebel or threaten to leave the house or something. At this point, your dad/mom should get serious and pissed. I mean fucking pissed and use an ultimatum. You can't let him step all over you guys. I know what it feels to have a little bro and to want to protect him and make sure he grows up as well as you did or even better. Also, your parents should not be like his laid back friends. There needs to a line of respect and to remind him of the relationship they share, father/mother and son. This is the time to get his act together, don't let this spin out of control any further.
