Absolutely untrue as the only markets we see this in are ones which are heavily regulated. And we're not talking safety regulations, but regulations to shape the market, which is likely impossible to keep from being corrupt (easy to believe if you've ever met an actual human being). I'd bet 50% of states have explicit laws limiting the number of hospitals in areas to protect county/state hospitals from competition, leaving many urban areas without high quality care, and yet somehow, through some chain of conspiracy theories, capitalism is to blame.
