We need India to get rich ASAP, so Indians can start paying for it. :-)
Trials are punishingly expensive.
Edit: protocol development. Drug interactions. Poisonings, Doctor education -- er, marketing. Incorporation into manuals. There's a lot that happens after the research talent has strutted its stuff.
Edit edit: oh, yeah developing manufacturing and logistics as well. The 'D' part of "R & D" is usually over 95% of the total for a reason.

Frankly this system is already deep into market failure in the US and should be reformed anyway. We are not getting important drugs approved here because they can’t make it through approval despite track records of safe and efficacious use in hundreds of millions of people. That’s an intense life-wasting market failure.

You might not get them to admit it out loud, but Big Pharma sees the USA as the cash cow that funds R&D for everyone on the planet. If a potential product can't or won't ever make it to market in the USA, or if there aren't enough potential patients in the USA to be prescribed said product, then it might never get off the drawing board.
It's (unfortunately) that simple.
