Actually, we have one of the best healthcare system in the world, it has flaws, sure, but we have something damn good: You break a leg? just go to the hospital, if you're Canadian and can show your card, it's free buddy. In the us how much it is for a broken leg? Last time I looked, it could go as far as 25 000$ depending of the states and a surgery is... well, beyond imagination. With no insurances here, you have the same treatments as anybody. Sure, if you have some special insurances you can go to private clinics and it goes faster, better service etc but bottom line is: without insurances, you can have the adequate treatment to fix your problem, even a very important surgery. When my brother had a cranial trauma and almost died, he had one of the greatest specialist in Canada upon his case, we had no special insurances for that matter. I think it's great.
Our biggest problems is that for some services, the waiting time can be very long, not for every single one of them but for a couple. That's why we don't have THE best but one of the best. I think that a similar system could work damn well in the US, if you could afford to pay more than 700 billions for fake WMD, you can sure afford this. The lobby of private clinics and insurance will be terrible but it could work, most definitely, it would just have to be adapted to your legislation but after a few tweaks it should work just fine. The problem in fact is not the idea to put such healthcare but the way Obama wants to design it that is wrong.
