A more plausible model is that doctors help sick people a lot, and are totally useless to healthy people. From that point of view, consider the American system of providing great health care to people with stable lives and good jobs, and sparing no expense on attempts to save people who are beyond help, while denying treatment to the unemployed and to people with "pre-existing", i.e. long term, medical conditions. It's almost like they're trying to exert the most possible effort for the least possible effect; like someone has memorised the triage chapter of a first-aid manual, then set out to do the exact opposite. Oh wait, they make lots of money that way, so it's all good.
