> This argument has always seemed pretty silly to me. Why, if this is how the market for medical services worked, would medical services cure any problem, when they could find ways to milk those problems for recurring revenue? Why aren't malaria or stomach ulcers "chronic manageable illnesses", rather than curable ones?

Yeah, surely if you were the first company to work out how to cure e.g. back pain or cancer you'd make an insane amount of money so you wouldn't keep it under wraps. Who exactly would stop you going to market with it? It's a silly conspiracy theory in my opinion.
