But those ways of being rational are not independent of one another, so it's rational for a drug injector to share needles because of a stupid decision that's made by a politician, and it's rational for a politician to make that stupid decision because they're responding to what they think the voters want.
Pero esas formas de ser racional no son independientes una de otra. Entonces es racional para un drogadicto compartir agujas por la estúpida decisión hecha por un político, y es racional para un político tomar esa decisión estúpida porque están respondiendo a lo que creen que los votantes quieren.
