Hospitalization is terribly expensive. False -- it is only expensive because you are being ripped off. In general hospitals are paid 1/4 or less of what they bill. That is, most so-called "terribly expensive" health care -- the worst kind -- costs one quarter of what you're told. Could you afford that, if you had to pay cash? Probably -- but you are charged 4x as much if you try to pay cash. Isn't threatening you with bankruptcy if you don't buy something by jacking up the price for cash .vs. so-called "insurance" better described as extortion?
Drugs are terribly expensive, especially for chronic conditions. False -- for a whole plethora of common chronic conditions you can today buy a year's supply of drugs for a couple hundred bucks. Literally. You're led to believe otherwise, so you sign up for "insurance" that then winds up costing you more for your drugs (in co-pays), usually double or more, than if you paid cash! The insurance companies love this. How do you feel about being systematically robbed?
Medicare supplement insurance coverage is a good idea. Generally false, for the same reason. What it costs exceeds what it pays in nearly every instance. Now you know why there are ads all over the TV for it -- it is, for most people, a zero-value rip-off.
Malpractice insurance is terribly expensive and thus drives up the cost of care. False -- it is a vanishingly-small part of the cost of operation for a doctor, hospital or other facility.
"Uncompensated" (or "charity") care is a big cost of operation and is responsible for the cost problem. False -- this is a raw lie. Most hospitals spend far less than 10% of their revenues on "uncompensated care."
Tests are expensive. False -- most tests are very cheap, with many under $20. They're only expensive because you allow "insurance" to pay for them, and the providers mark them up for so-called "list prices" by as much as 1,000%.
The real problem is monopoly and other unfair practices, all of which in other industries would lead to immediate felony indictment under consumer protection statutes or The Sherman and Clayton Acts, with the latter carrying 10 year criminal felony penalties and $1 million fines per occurrence. TRUE.
