Kids make me laugh. Look, they brought you into this world. They put a roof over your head. The majority of your possessions are thanks to them. If anything, you owe them... tens of thousands of dollars. The average price of raising a child, putting them through school, hospital visits, clothing, food, etc. Although your situation does sound shitty, kids never have the right to complain in this regard. Just wait until you emancipated then you can do what you want with your cash.
Except that they chose to do that well beforehand and knew what they were getting into. They didn't write IOUs for every expense made at his cost and therefore all of it was a gift from them. He, on the other hand, has his job for another reason. Perhaps he's saving for something, or whatever. It doesn't matter. If they take money from him, it's stealing.
What you're talking about here is emotional blackmailing: "Well, we did [THING X] for you, so you're a horrible person if you don't do [THING Y] in return". If a parent does this, he/she is a bad parent.
Also: those saying "well, it's okay if the family needs it, I guess," you know what that is? Child labour. You know what child labour is? Illegal.
