There are a variety of reasons for this. Different reasons have different most effective solutions. If we choose as our general solution something that has narrow scope of significant positive effect and wide scope of moderate negative effect, I'd say we've chosen poorly as that will harm society as a whole rather than help it. Which is why the hard task of getting those numbers is worth it.
