>treat AIDS, and the patient will keep buying more treatments as long as he lives.
This is oft-repeated but it doesn’t pass the smell test. All it takes is a single principled academic to blow the whistle if there was any active suppression of cures or even research on cures.
In order for that quip to hold water, literally everyone involved in medical research would have to be a corrupt monster maintaining a worldwide conspiracy to keep sick people coming back for more treatments.
There's no conspiracy to suppress cures, but research funding is more attainable the larger the eventual profit.
