Good article. I think the only thing the author may have left out, though, is profit motive. It's not just simply to make our lives better, which may be what he is implying without even writing it. Without profit motive none of the good deeds described would be done at all, the benefactor would be working elsewhere, improving our lives in a completely unrelated way. And without profit motive we wouldn't just have rancid crumbled chips, we would have no chips at all - unless we made them ourselves.
