There's a difference between being responsible and acting in good faith and letting your narrow self-interest damage others.
When a chemical company invents a pesticide or hebicide that enables farmers to grow more food or avoid some sort of difficult or dangerous manual labor, that's a good thing. When pesticide has wider-ranging effects that can negatively effect the greater environment or economic fortunes of others, and that same company obfuscates or actively funds research to deflect attention, that is a bad thing.
Many people who claim to be "capitalists", but who are actually aspiring plutocrats, have a very shallow understanding of how markets work and have picked up this near-religous faith that whatever makes a business happy is good. That's not necessarily true -- business also needs to be a good neighbor. If one of the side-effects of your business activity is contibuting to the destruction of a form of life that is a key part of the food chain, you are an enemy of free markets and our free society.
