This is an oft-repeated sentiment, which I've never seen actually happen. The free market pursues profit. Not customer needs. The most "efficient" thing to do is fleece customers when they're at their most needy: when it's either pay up or die. How do you explain all of the successful socialized medicine in other countries, if government involvement = healthcare sucks?
