You do realize that before the ACA, the average insurance company besides Medicare (which ran around 20% administrative costs) ran something like over 60% of it's costs as administrative costs, right? More was being spent on the bureaucracy that they themselves made than they did in actually paying for people's coverage.
For almost every insurance company in our nation they followed the same trend.
PS - The "Medicare/Medicaid" figure is bullshit to put that way, it's MEDICAID that has $550b of help - MEDICARE gets $50b and only indirectly (Pharmacy and Premium assistance for Medicare is done via Medicaid which is that entire tally) - Medicare, besides the two caveats I listed there which are helping poor people that have Medicare is completely self-sustaining.
Lets say it really was 60% administrative costs. Who cares? That must have been the most efficient way to do it. Saying otherwise is claiming the insurance companies are all incompetent at running their own businesses or they had a motive other than money, which are both ridiculous. If they were spending that much on administrative costs it was because they were seeing returns from doing so. Forcing 80/20 on them can only reduce their efficiency and make stuff cost more. The myth that insurance companies were making a killing denying claims just can't be true when their profit margin is that low. They could have done 80/20 themselves at any time if that would have increased profits. Why would they waste money on "unneeded" bureaucracy for no reason?
Obamacare can be a win from a social justice standpoint, now people with pre-existing conditions that aren't their fault can actually get insurance, and now so can poor people that couldn't afford it before. But you have to remember that those new rights cost money. Claiming Obamacare saves money is the height of stupidity. It does not address the out-of-control costs in any way, and those people now have these rights because you are subsidizing them.
With regards to Medicare, $50 billion is only the Part A deficit. Most people don't realize this, but the payroll tax for Medicare is only supposed to pay for Part A, and it's only covering ~80% of Part A costs at the moment. Part B is entirely financed by deficit spending and so are the shortfalls for Part D. (the premium you have to pay to get Part D comes nowhere near to covering the costs)
Also, I work in a hospital lab. I have access to our lab's price list, which lists what we pay for all the chemicals and reagents we use. It's very interesting to compare these prices to, say, what Sigma-Aldrich charges the public for exactly the same reagents. I can tell you with certainty that the markups for our lab start at ten thousand percent and go up from there. For example, yesterday we got a delivery of a 1% silver nitrate aqueous solution from Dako, they charge us $5,950 per liter for this. Remember that's a
1%aqueous solution, which means we are buying silver nitrate for $595
per gram.That's over a 20,000% markup from what you'd pay to buy reagent grade AgNO3 from Sigma-Aldrich. You can buy pure, solid platinum for less money than they are charging us for this. This kind of shit pervades the entire healthcare industry and is the main reason everything costs so much. Just like a caterer triples the price when they figure out they're catering a wedding, companies will just add a few zeroes to their prices when they realize they're selling to a hospital. In my opinion, this is also the main reason insurance companies were all administrative costs, it wasn't to deny claims, it was to try and root out this ridiculous price gouging as much as possible.
