Therefore, any market for individual purchase of healthcare (whether via insurance or directly) can only have faulty price signals.
Systems based on markets with faulty price signals are wide open to manipulation.
The perpetuation of such markets is contemptible, and particularly so in the case of healthcare since there is a straight line to be drawn from dysfunctional systems to human suffering.
Perhaps it is just to make sure they always get the max from the insurance companies. Or maybe they are able to write off the portion that the insurance company won't pay as a loss or bad debt.
Personally, I believe this practice to be outright blatant fraud. There is a complete lack of price-transparency for the end-user, whether there's an insurance company involved or not. And for people who supposedly champion the so-called "Free Market", Congressional Republicans are certainly quiet on this one issue, when they're criticizing the current healthcare system and regulations.
The real problem is that I rarely have any reason to ask if my insurance is going to cover all of it.
