If people loved others as much as they love themselves

If we lived in a world where everyone loved other people as much as they loved themselves, I don't think that the world would change very much. Some people love themselves a lot, and others almost not at all. In the world today, everyone is treated differently, too. If one person loved themselves a lot, they wouldn't affect every single person. Some would still not be treated the same because there would be people who didn't love themselves very much. Also, there's the question of whether people would treat others as much as they loved themselves on the inside, or the outside.If someone showed on the outside that they loved themselves, but secretly they didn't on the inside, then how would they treat others? Really, I think that this world would have to become a reality in order to know for sure.
