Government comes in and says it's illegal to drop your insurance. Also here's a massive regulatory wall to prevent competition. CEO of the company who has no competition and legally can't lose customers acts exactly like you'd expect in that situation.

If you want to fix the health care, you don't shoot the CEO, you dismantle the government.

Instead, the government will see this outrage and likely add more regulations to make the public happy, thereby making the problem even worse.
