No, it is not feasible. The pharma and med-device industries spend well over $100B a year in R&D. Government, academia, and charity money is much, much smaller.....perhaps $30-40B. Also, much of this money is focused on very basic concepts/general science, not drug development and commercialization, which is very risky and massively expensive.

I work in pharma and my franchise of products made $1.8B last year. Minus out costs and rebates, our net is about $1B. Well, we just initiated a phase III clinical trial for a new factor Xa inhibitor for stroke prevention. This one particular trial will cost over $1B and there will be more to do afterwards.

So, all of the money my company made on my franchise was just spent in a blink of an eye. And phase III trials only have about a 50/50 success rate. Very risky.
