JUST ANOTHER COMMODITY:

 As I described in a recent PwC Health Research Institute report, they include:

Vertical integrators such as Cigna and Express Scripts, which hope to build efficiencies of scale and condense the value chain

Employer activists such as Amazon, Berkshire Hathaway, and JPMorgan Chase, who seek a better health care offering for their employees

Technology invaders such as Google or Uber aiming to gain better footholds in the industry

Health retailers such as Amazon looking to gain market share by better understanding consumer desires and behavior and provide some types of health care directly
