My evidence is that I've lived in countries with market-based healthcare (Thailand, Mexico) and countries with socialized healthcare (Canada, UK), and the market-based healthcare is always infinitely better. My wife had to wait months to see a psychiatrist in Canada, before we moved away. WTF? In Thailand it's like $50 and you get in right away.

Why are you bringing up the US? It's not market-based healthcare.
