Here's another story that just happens to be true: I'm on Medicare, don't make 85K individually, my wife and I together don't make 170K. We pay a little over $100 a month each for Medicare part B. It's not a huge burden, no, but neither is it free. The cost also goes up as the patient's age goes up.
Yet another: Medicare pays only 80%. Doctors don't charge just what Medicare will pay, but that plus the patient's 20%. That's why seniors still need a supplement. If the doctor's visit is $100, and Medicare pays $80, that's not a big deal, but if the cancer cure costs $200,000 and Medicare pays $160,000, most of us will need some help.
