While I agree that lacking empathy is a horrible thing, I would argue that corporations are greedy on top of the no empathy part (note how I made a distiction of a "non psycopath way). I may have misinterpreted the OP's original question, but I would have to put greed in the category of an emotion/ feeling. And while I agree that "logical" responses vary from person to person, if the person has absolutely no emotion, aka outside factors, influencing their decision, I could imagine that their response would be the best possible. But I agree, the success of human beings can largely be attributed to the "herd mentality" and people working together for the most part.
