One hospital bought a CT machine. Doctors who are the most important customers for any commercial hospital, began to sign contracts with that hospital because it made access to the CT machine for their patients easier. The other two local hospitals had to compete and bought their own. Now there were three machines and only enough patients to support one of them. That didn't reduce the maintenance costs. The cost inevitably is passed on to all patients. This is only one example from hundreds where competition led to unnecessary cost from duplication. Add to that the overhead for people who specialize in insurance billing because the competing companies are different and very complex, add to that the profit for the investors in the hospitals, the profit for the investors in the insurance companies and that's not even touching the similar stack for pharmaceuticals and supplies. That's not even adding in the cost of delayed and emergency treatment due to lack of preventative medicine for the uninsured and the under insured. All of that adds up to the $99 bag of $0.99 saline that comes out of your pocket one way or the other.
It would be difficult to create a more wasteful or expensive system if you set out to do it on purpose.
