Drug and Oil Companies

I know it's fashionable to diss the drug and oil companies for overcharing us, polluting the environment, contributing to destabilizing regimes, and not providing resources to poor people...

But if we want to really look at the big picture and the scheme of things, shouldn't we be kinda sorta happy about all sorts of drugs that help save people's lives or at least make them feel better and the enormous improvements in living standards which have been fueld by the access to relatively cheap petroleum? I mean - are these really the boogy men we make them out to be? And by doing so, do we discourage smart young people to go into these industries to help make even better products?
