Credentialling of doctors as it currently stands is an artificial guild system which restricts the number of doctors. It doesn't make medicine safer, but does increase doctor salaries.

Drugs also reduce the need for hospital stays and thus costs by curing or preventing conditions that would otherwise get worse.
