Why Americans are outraged over health insurance — and what could change

Many patients, advocacy groups and experts say the industry and U.S. health-care system are flawed or broken entirely.

But there is less consensus on the root cause of the issues around insurance and how exactly to fix the industry.

Luigi Mangione , 26 , is accused of fatally shooting Thompson outside the Hilton hotel in midtown Manhattan on Dec. 4 , as the CEO headed to the annual investor day of his company's parent.

Some people aired their frustrations with the company's practices on social media when reacting to Thompson 's death.

Insurers are mostly paid by employers and government agencies, which set many of the rules around the coverage they offer.

Some industry experts argued it is necessary for insurers to control costs under the current health-care system.

The incoming administration under President-elect Donald Trump could push for more transparency in the health-care industry.

Until any significant changes occur, patients can "really try to take control of their own health," says Michael Hinton .

"There are other methods of change — and that could look like trying to be your own advocate," Hinton says.
