Keep in mind that includes inefficiencies and redundancies in each of the thousands of insurance companies which are themselves incredibly redundant in every respect, but especially so in claims processing. I'm guessing administrative and systems redundancies actually run more like 75-85% over a single payer clearing house.
And you would be wrong. the inefficiencies you speak of actually run, on average, about 350% higher in the U.S. verses all other industrialized countries who offer some form of public option: about 5% versus our 18%.
Look, the 'debate' is over. The experiment's been done since WWII in all industrialized countries including our own. Our employer based private health care system sucks ass: it's a joke to the rest of the civilized world, it's near the bottom overall regarding outcomes and stats (despite JayB's endless stream of 'my wife's fresh out of med school so I'm an expert complete and utter bullshit' and it's incredibly cruel. Witnessing what is happening to a large number of friends makes me an expert on that one.
We need a strong, not for profit, public option. The exact form doesn't matter than much: they all work fine elsewhere and herere where they are used.
