As an American who has lived abroad for decades, I've had the chance to experience single-payer systems firsthand. I did a TV interview in Manhattan a few weeks ago, laying out in plain language the problems with the current US system and how ideas from abroad can help. I have cut this interview (entitled "Beyond Sicko: What you really need to know about health-care reform") into four short parts and put them up on youtube.
This is an overview of the series:

Beyond Sicko: Part 1 covers the WHO study putting USA at #37 internationally and how ideas from other countries can benefit the US health-care system.

Beyond Sicko: Part 2 looks at preventive medicine, the power of US pharmaceutical companies and questionable choices of the Obama administration and the Senate Finance Committee.
