Jeff Bezos, Warren Buffett and Jamie Dimon — the billionaire leaders of Amazon, Berkshire Hathaway and JPMorgan Chase — sent shockwaves through the health care industry yesterday when they disclosed plans to start a not-for-profit company with the hope of reducing medical costs for their employees.

Reality check: A lot of companies have promised to "disrupt" health care, but few have succeeded. The U.S. still spends wildly on a system with poor outcomes. It's far from clear this new conglomerate, premised on a vague PR, will be able to do any better.
