I'd get yourself checked out for paranoia!
While of course it is ridiculous to automatically assume every pharmaceutical company is operating purely for the benefit of Mankind, making the assumption - as you clearly have - that these "toxic evil faceless money-grabbing corporations" (or to most people "corporations") are there purely to make a fast buck and sod the collateral is both incorrect and significantly more harmful as far as I am concerned. The whole process of drug development is of course flawed, but it does tend to work (eventually!) even if the investment and material costs are enormous and there's no guarantee of success. If I invested money in such ventures (and I have) I would hope for some sort of dividend (not just literally) from the product my money as an investor has helped develop. It's called Capitalism, and when controlled by appropriate checks and balances, it's the best system we have, old chap, or at least the alternatives are too horrible to contemplate...
