From experience, an Australian doesn't have the correct frame of reference to even engage in the US healthcare debate. I have tried to understand the issues many times but it comes from such a fragmented starting point it's difficult to understand unless you've been in it for a long, long time.

Your points about uninsured are valid, but it's much more complicated than just saying 'hey, you guys should insure everyone'. So I generally try and observe from the sidelines.
