I notice how the prices are not rationalized beyond "because that's what Pharma charges" because of rarity of the illnesses, etc. But there's no concrete 'why'

I notice how the prices are not rationalized beyond "because that's what Pharma charges" because of rarity of the illnesses, etc. But there's no concrete 'why' the prices are what they are. It seems they charge what they can get away with charging (it is a market economy, after all). It's not goodrx's fault in their reporting (bravo to them, in fact), it's that there is no transparency into that industry that would provide such a breakdown (that I know of -- surely never see it reported).
