An ounce of prevention, isn't cheaper than a pound of cure?

That's according to the non-partisan US Congressional Budget Office (via ABCnews and GregMankiw):

Although different types of preventive care have different effects on spending, the evidence suggests that for most preventive services, expanded utilization leads to higher, not lower, medical spending overall.

This has obvious policy implications given how much we've generally all been engrained with the idea that prevention is easier/cheaper than dealing with bigger problems that result.
