I don't mean to offend you, but I think you're the one that's biased. If you're working for a private company doing research, then OF COURSE you're whole thing is going to be profit motivated, but I don't think that's why people go into the sciences (and I don't think that's why YOU would have gone in). There's a lot of money to be made in the medical sciences, particularly in the relatively new field of genetic research, so I think you're seing a disproportionate number of money grubbing assholes in your field, but don't let that tarnish your view of science in a broader sense.
