Amazon, Berkshire Hathaway, and JPMorgan Chase & Co. announced Tuesday that they are teaming up to improve health-care options for their U.S. workers. The three companies plan to use their scale and joint expertise to help reduce costs and improve employee satisfaction in health plans, using an independent company. The companies said they hope to use a fresh approach to solve longstanding problems. "The ballooning costs of health care act as a hungry tapeworm on the American economy," said Berkshire Hathaway Chairman and CEO Warren Buffett, according to MarketWatch. "Our group does not come to this problem with answers. But we also do not accept it as inevitable."
