Below is an excerpt from a recent post on Wait But Why (see full - in all senses of the word "full" - post, here) :
This topic probably deserves its own full post at some point, but I just couldn't not take down this quote because it largely summarized a recurring conversation I had with many good friends in the last few months.
We face this kind of moral questions on a daily basis, though at a much smaller scale for us regular-Joes-and-Janes. We tend to think of these corporations and specific industries as "evil", or the driving force of social and environmental instability. In reality, it's just a bunch of regular Joes and Janes sitting on the (extremely) long end of a seesaw, catapulting the world across from them - not by malicious intent, but by something as natural as gravity: our own greed. Not that I don't think Joes and Janes in positions of power shouldn't act responsibly and, dare I say it, "morally". I just think that, having been born into a culture where personal greed is heroically exemplified, it would require taking some adult classes on moving away from the default.
