Tough one. Lower the costs of drugs and there is less incentive to create them.
Think about smart people...the ones who do this stuff. They can become doctors, lawyers, bankers, etc. They'll only keep going into medicine, and specifically pharmaceuticals, if there is a nice enough profit motivation. Otherwise, they'll all become bankers and make tons of money. We could throw IT into that mix too...do I want to design a drug that could save lives and make ok money...or go design the next twitter and make a boatload of money...which would you pick?
