I can understand it, but it's basically a classist system. The advocates are saying rich people are better than everyone else, they should be able to bribe their way into better health care because they can afford to. A single payer system that puts everyone, regardless of race, class, age, at the end of the line - and as they do not like how things work, they fix it. What's important is creating the auditing mechanisms for identifying and evaluating problems, prioritizing them, and then getting them fixed.

But the reality is, the for-profit system already forces people into a substandard single payer system in a huge portion of the U.S. where there's only one insurer, not least because health insurance is an anti-competitive business but aren't regulated per competition law.
