Every player in the US healthcare / health insurance "system" has adapted to the regulatory niche they play in.

If Americans had the fortitude to have grown-up conversations about what should be socialized, how care should be rationed, etc, the public could exert some control over the design of the "system". As it stands, the "system" has mostly been shaped by corporate interests while the public has been distracted by inflammatory rhetoric pumped-out by all the entrenched players designed to play to partisan feelings about "fairness" and "freedom".
