The very idea that every single person could possibly work towards one ideal is nonsensical. Just as in every other breed of animal, in particular our simian cousins, an 'alpha male' will always take control of the group in its' entirity. Furthermore, in order for everyone to be equal, we would need redistribution of wealth and resources. If you like that idea, fine, but try selling it to Joe Bloggs, happily domiciled in his newbuild house with a BMW on the drive. Oh, and we'd have to eradicate a classic human trait; greed. Fight the power, comrade.
