The only "innovation" of capitalism is intermediation, otherwise called "rent-seeking". One of the big lies Big Pharma tells you is that R&D is expensive but the actual R&D is done primarily by government funding and research at colleges. Big Pharma spends WAAY more on marketing. The only real R&D Big Pharma does is patent extension. Patents have a life so companies will make minor changes to the molecule or the deli…
Not an expert, but my understanding is that the kind of basic science R&D done by the government and academia is the simplest and easiest type of research to do by far. As it was explained to me- anyone can invent new compounds, the really really really hard low-percentage stuff is trialing that those new compounds are A) medically effective in people, and B) actually safe for people and don't have strong side effects.
Also, I believe that if academia actually does invent something novel & useful, they license it out to pharma companies for a % of the profits. Big universities are not shy at all about licensing their IP
