It could also be the perspective that you can really only try to control your own lot in life. Is it not possible that by focusing on my own welfare, I am more productive and happier? And that by trying to float other boats, I am distracted and less happy? I don't subscribe to the OPs opinion, necessarily, just pointing out a situation where it might be better to just take care of yourself.
