>The reason "return on investment" matters in a financial sense is because big, bad, greedy corporations only care about their bottom line.

I would argue that it's ALL corporations that only care about their bottom line. The entire reason a corporation exists is to make money, any other considerations like employee well-being, care for the environment, etc are driven entirely by either legal requirements or a need to retain talent in order to make that money. Any corporation who successfully projects an image of being "different" just has a good marketing team.
