Figures you wouldn't know. It's the proper term, but I'm sure you're just kidding me, you're so learned.
As to "excess dollars" you mean the hundreds of millions of dollars that are sunk costs when drugs have trials run worldwide and fall short of FDA approval causing the companies to walk away with nothing but a financial loss? Those costs?
Oh, you mean the payoffs to MDs so they'll prescribe the company's drugs? Pharma reps can't hardly give a Dr. a pen or a coffee cup these days.
The number of drugs that are brought to market is a reflection of market forces. Pharms often shut down promising studies because their internal marketing studies foretell they will not recoup the development, packaging, distribution, and marketing costs. Or the patent will run out before they can bring it to market and the jackal generic manufacturers will copy their intellectual property without doing a pennies worth of R&D. That's fair.
The NIH does sponsor drug discovery already.
