I knew this in theory, but never really thought much about it.
I need a flu shot, so the company that makes the flu shot needs to be compensated (paid), and the nurse that knows how to inject it into my arm needs to be compensated, and that's it. The manufacturer and nurses provided a sufficient infrastructure to administer flu shots.
But in America, I also have to pay a bunch of insurance companies. I used to make 6 figures as a programmer in the insurance industry. I knew my salary ultimately came from the high medical bills everyone pays, and while I didn't blame myself personally for a nation wide problem, I would have been happy to see my job and my company rendered obsolete and all of us move onto more useful jobs.
I want to see a political cartoon where someone gets a flu shot and then does their patriotic duty, opens their wallet, and starts handing out money to half the nation. In the end, there's even a few bucks left for the nurse.
I exaggerate a bit. In truth I think about 20% of US workers are involved with the healthcare industry and the surrounding insurance and other supporting industries (if I remember correctly). I really do have to pay all those people every time I have a medical bill.
Fixing healthcare costs will require a lot of people losing their job, and that wont be popular.
