He implies the reason is that US voters are ignorant. As well as being a bit impolite I'm not sure that's case. The strange US system started I think as a stitch up between US insurance companies and Richard Nixon and there are ongoing vested interests making it very hard to change.

Here's a survey result:

>Even Republican voters seemed to disagree with certain conservative ideology on health care. The Hill-HarrisX survey found that 26 percent of GOP voters said they wanted the government to stop paying for health care, while a total of 53 percent favored some form of universal government-provided insurance. Twenty-one percent said they want to keep the current health care system in place.

So it seems more like the public would prefer universal government-provided insurance but the political system is not good at following their wishes rather than those of the various lobbyists etc.

I think he points out why: people don’t know any better.
