Don't overhype the new health care venture

Doctors' coats with Amazon, Berkshire Hathaway and JP Morgan Chase logos

Even if Jeff Bezos, Jamie Dimon and Warren Buffett come up with ways to lower their own corporate health care costs, it’s highly unlikely their new health care venture will move the needle on overall health spending or other dimensions of the health cost problem.

The odds: Bezos, Buffett and Dimon are big names — big as they come — but the history of health care is littered with business titans who have declared war on health care costs. Amazon, Berkshire Hathaway and JPMorgan Chase may be able to get their own costs down, but that doesn't mean they can do it for anyone else.
