Those TV ads. We have ads for prescription drugs. Drug selection oughta be the doctor's job. When patients come in, asking for drugs they saw advertised on TV, a lot of doctors will proscribe them thinking they don't hurt and it makes the patients happy. Health care costs would decrease if those drug ads were off the air.
Then there are the TV ads from lawyers, looking for malpractice plaintiffs. Those drive up the cost of health care. Back in the good old days it was unethical for lawyers to advertise at all. We ought to revive those ethics.
Finally there are the ads from power wheel chair makers claiming they can get medicare to pay the whole cost of the power wheel chair.
These health cost increasing ads are on Fox News all the time. More often than the GEICO gecko.
