Oh come on, this is dishonest. Your doctor doesn't work for free. Someone else is paying them if not you. Possibly the inhaler is also subsidized.

When healthcare cost is being discussed, the cost on society should be what's being discussed, not to what extent it's paid for by tax money. Those are two different things and they're only slightly related (in that if healthcare is perceived to be cheaper, people might use it more, which may drive up total cost) (or drive it down through better prevention).
