From what I have read/heard, the US is among the worst.
From what I have noticed at work, there are ways to get just about everything payed for(as far as health) if you don't care about being a productive member of society. Almost all of my patients on Medicaid get better health care than I have ever had. They have better TV's and furniture. They spend more time with friends and family. Many of them are younger and healthier. It all just depends on how you want to live your life.
I feel bad for my VA patients and medicare patients in the nursing homes. They are the ones getting MAJORLY screwed.
