Saying Medicare can't negotiate drug prices is an over simplification.

For physician administered drugs, the gov't has said "we will pay an average of what everyone else pays". No negotiation, just defacto proclamation of what Medicare will pay.

For prescription drugs, Medicare pushes negotiation to private insurers who actually provide the coverage. They do negotiate with drug companies, often getting very steep discounts. Also, Medicare has said to drug companies "once a patient hit the donut hole, you need to give a 50% discount". Again, no negotiation, just a "if you want to do business with Medicare, deal with it".

So yes, they don't negotiate drug prices, they just tell the drug companies what they are willing to pay.

The word 'free' ... like the words 'nature','organic','improved','good', and 'god' ... means what you want it to. You may, of course, try to convince people that you mean something else entirely.

Of all such words, the word 'democracy' is possibly the most-abused.
