It seems the majority of people, if one were to pursue this philosophy, ought to be left to oblivion. Entanglement with them will only result in encumberance rather than advantage, even if you were to attempt to selflessly better them without regard to the benefits to yourself, typically they would be incapable of making use of your assistance.
If you seriously go through life with that much of a sense of superiority, it would be no surprise at all to be socially isolated. I don't think that way. Most people are important and useful to humanity at the individual level. My default is to treat all people as if they are, and that default assumption is generally born out in my interaction with people in many settings. I don't merely seek PERSONAL advantage in dealing with people, but the broader advantage of a better human society for all.
