Opinion: Why health insurance companies are doomed

It's that time of the year. No, not Halloween, but something almost as scary—open enrollment season. It's time to choose among the many plans offered through the various health exchanges as part of Obamacare, among the variety of Medicare Advantage and prescription drug plans offered by private insurers as part of Medicare (for those who are age-eligible), and, for the 62% of employees who are have the opportunity, time to sign up for an employer-sponsored health insurance plan. As we struggle to make sense of the health insurance landscape, it's a good time to consider why health care costs in the United States are so high and outcomes so relatively poor and, more importantly, what the future is likely to bring.
