I just noticed this attracted some downvotes and comments. I should have been clearer. My curiosity was piqued by this:

I wonder how many small pharma startups are successful. Is this really "effective separation of concerns"? Seems more like standard capitalist market dynamics: allow small-fries to take all the risk -- those that sink disappear; those that succeed might get bought out.
Is this really the best way to drive innovation in pharma? But... that's a discussion about markets.
Also, without researching the history of every drug produced by any major pharma corp, I can't blithely accept whether acquisition of "promising drug candidates" is or is not a "major input" to their pipeline. I'm not denyingwhether this happens, just asking to what degree -- just saying "citation needed" for that particular point.
I'm certainly not denying that some small pharma companies are successful, and that some get bought up by large pharma companies. That wasn't my question, and I should have been clearer.
