I think both sides are extremes just because in all likeliness we wont move to either of them.

But we're already at the one extreme! And it's failing miserably. Everyone who wants to keep it privatized must feel immortal. The cost of something as simple as a broken leg can be up to $35k... how many people have $35k laying around just in case when a large portion of the working population doesn't even make that much in a year?
