the prevention people tried to make the case that taking action to detect and treat disease early would bring down costs. I, among others, argued this was nonsense. The real way to bring down health costs is to eschew prevention and let disease progress to the point where death comes quickly and without warning.
The earlier you catch a disease the more likely you are to spend a bunch of money treating it.
¿Vale? Se salvan vidas, es un argumento. Pero entonces la justificación es ésa, no me digan que prevenir sale más barato.
