> in some part of europe, we have national healthcare so basically people don't think they are paying their medications, like there was some magic money.

Europe is a big place, buddy. Which particular part are "we" from today?

NHS England has NICE (National Institute for Health and Care Excellence), which does the cost-benefit analysis for all medicines prescribed, nationally. It frequently decides medicines aren't worth the money. If you, as a private citizen, want that particular medicine, you can waste your own money on it. NHS England does not have a moral hazard problem.

The NHS also spends money trying to convince people to exercise, eat well, lose weight, not smoke, look for early signs of cancer, etc., because they find that relatively tiny amounts of money on these campaigns results in massive, massive savings from not having to treat so much preventable disease later in life.
