<pessimist> Cheaper would also mean less revenue generated by ongoing symptom control medication. (Asthma inhalers for example: ~$13.4B global 2021, CAGR=20% !!)
There is less business incentive these days to prevent or cure disease from what I can see. We have prevented a lot of the really big diseases that scared the hell out of people in history. (with some notable exceptions)
Today a cured person is a lost consumer to a pharmaceutical company.
The only solution to that issue, that I know of, is some form of government incentive to artificially subvert the natural market pressure but that is distasteful in free-market countries and money "invested" in political campaigns can "motivate" politicians to steer clear of those waters.
