I was never convinced by the argument that patients and doctors can't be trusted to request the care they need, and would overconsume healthcare unless strictly constrained. I mean, it will definitely happen (I know some hypochondriaques), but to what extent? On one hand, "overcared" patients would likely avoid serious illness through prevention, so it's not obvious costs would explode. And on the other hand, there's a limit to how many useless treatments you can push onto patients. However, there seems to be no limit to consolidation and price gouging...<p>I'm glad this article provides real data and solid analysis to back my intuition.
