Would much rather have single payer as well.
I think it's the clear way to truly lowering costs. When you have a single payer, you have such leverage on costs of treatments because it's a take it or leave it situation. Either take $X for an x-ray or don't do it and you gotta assume that if it's still profitable, it will be done. I know Japan, in the case of x-rays said $X is what we'll pay and the industry responded by pushing manufacturers to create cheaper x-ray machines. I believe this was done by cutting out some of the more advanced and lesser used features on the machines, but that's, again, a trade off you have to make.
