As for insurance costs, I found this.
"In 2014, U.S. health care spending increased 5.3 percent following growth of 2.9 percent in 2013 to reach $3.0 trillion, or $9,523 per person. The faster growth experienced in 2014 was primarily due to the major coverage expansions under the Affordable Care Act, particularly for Medicaid and private health insurance. The share of the economy devoted to health care spending was 17.5 percent, up from 17.3 percent in 2013. "
My recollection is that insurance takes around 32% off the top, including the cost of the clerical services on the medical care side. If that's correct which I don't have any evidence for, then insurance is pulling in around 1 trillion a year. That's a lot of money, and based on the para I posted above it would come to 6% of the American economy. I've read that admin costs in Europe and elsewhere are typically around 5%. Some of my numbers may be off but whatever it's still a huge pile of dosh.
Quoting myself here to update my previous post.
I found this on the subject of organized crime.
"The annual turnover of transnational organized criminal activities such as drug trafficking, counterfeiting, illegal arms trade and the smuggling of immigrants is estimated at around $870 billion, the UN Office for Drugs and Crime (UNODC) said."
If my calculations above were correct then this, $870 billion, is a little less than the $1 trillion the medical insurance industry costs the American economy every year.
However that's the Health Insurance Costs For Dummies version. I found some more rigorous academic analysis that provided a different and presumably more accurate picture. They factored in a lot of detail. For example the fact that American doctors spend an average of 58 minutes a day on insurance related tasks. And the overhead of insurance companies in isolation varied from 8% to 17%, not counting the assorted costs of interfacing with them. And differences between family doctor practices and hospitals etc. After a bunch of number crunching they came up with an actual annual cost of using the insurance industry to control the provision of health care of between $340b and $480b.
They gave some explanation for the large spread in the results. It depends partly on what you count. Do you count the cost of paying doctors for an hour a day of insurance work. Do you count the cost of the HR time companies put in. The cost of all the lawyers on both sides beavering away arguing about disputed insurance claims. I even found a number of hours the average citizen spent per year dealing with insurance and an estimate of how much that could be said to cost the country. I saw final numbers in several other places ranging from $280b to $620b.
That total includes Medicare, which has far lower administrative overheads, and ACA, which has higher than average overheads.
So they are only taking in around half as much as world organized crime instead of more as I previously claimed. Of course those other criminal groups actually provide a service to their customers. Like they give them drugs and guns. Not sure what I get from health insurance, other than a gigantic headache.
