Uh, dude, if it's that important to you you would have opted out. It's implied consent, just as occurs when someone is found unconscious and it is implied that we should treat them. >80% of people support donating their organs, while only 45% have actually opted in to the system. An opt-out system preserves the right of the small minority that want to opt out, while ensuring that half of potentially donated organs aren't wasted because a person was too lazy to check a box. It basically ensures that zero lives are lost needlessly, and, in fact, many are saved.
As to how much a doctor gets for an organ transplant, it isn't a whole hell of a lot. Transplant surgery isn't very popular amongst physicians because it doesn't reimburse well, the patients ultimately will either die or have to have their organs replaced (as they don't last forever), and you have to follow your patients forever post-transplant. "Sticking skin on people," or plastic surgery, is much better reimbursing but uses autografts, not allografts, and doesn't reimburse all that well either (hence why the guys who want the big bucks in plastics do cosmetic, rather than reconstructive, surgery). You can't transplant skin from person-to-person, but skin can be used as a temporary covering for burn victims.
