It boils down to a question of is medicine a for profit industry or not.
Respectfully, it does not. Insurers and financiers of medical care are not a part of this, as I am aware. The sale of organs is illegal. The process by which recipients are selected are subject to regulation and oversight in order to ensure that those selections are made with regard to medical condition and need. We don't need billionaires taking advantage of land scams to bribe transplant doctors to violate their ethics.
