One of the 'mysteries' of corporations is that they will either do nothing, or take an action that furthers their corporate interests. People don't seem to expect that of companies with a public face and seem surprised when they turn out to be just like any other corporate group. It's a coordination thing - coordinating a large group of people is so challenging only simple messages like 'make a profit' get through on…
No, it's a self-interest thing. Also known as greed, or selfishness. Do you honestly believe that if "being a decent human being" came with a simple metric like money, then companies would deviate one iota from pure profit motive?
Sometimes I wonder if people here are really this naive or if it's a case of "it's very hard to convince a man of something when his salary depends on him no believing it."
