It is true that in a purely profit based pharmaceutical research environment, one needs a whole bunch of profits to develop pharmaceuticals.

The question is, is that the best environment for the purpose? It has had great successes, but I wonder how many other wonderful drugs and other treatments might have been developed if the market for them wasn't such an important determinator.

And I wonder if the costs of developing drugs might be much lower if there wasn't so much potential profit to be made.
