Average "admin expenses" for private health insurers (and one *might* rightly call at least some part of that "profit") run around 16%. That leaves at least 4% for guess who? The shareholders. HTH.
For comparison, Medicare's administrative costs are around 3 per cent. Meaning, of course, the government is *vastly more efficient* at processing medical claims than is the private sector. But, as your guy in the White House made abundantly clear: we cannot have a government Single Payer Plan because that leaves all of Wall Street and their investors out of the profit taking business in our healthcare delivery system.
