Governments have done horrible things. Researchers have done horrible things. Religious Groups have done horrible things. NonProfits have done horrible things.
It's not about profits.
When you're designing a new engine, you might decide to use 10% more expensive parts to make it 20% more fuel efficient, but this additional cost might result in 10% lower sales, so the board decides against it since exhaust is just an externality. If those people were considered with ecology they might consider a lower rate of profit but instead take pride in the fact that they're helping humanity combat global warming while maintaining the standard of living.
It's easier to rationalize away "bad things" when making money is at the top of your value scale. I think it resembles the individualism of our age, people used to be more aware that they were a cog in the machinery of history, no one thinks like that anymore, it's all "be the best you can be" rather than "be the best we can be".
I agree. The purist free market ideology, for lack of a better term (or maybe Objectivism?), is a convenient justification for not dealing with difficult issues. 'The ideology says I can/should only care about money, so I don't need to worry about all that.' If only life were so simple that we could rely on an ideology.
