Syndrome from Incredibles said that "When everyone is super, no one will be." Is that true?

If everyone on Earth had technology that simulated superpowers like he wanted, would that really make the people born with superpowers normal? Even if he killed all supers, would that still make everyone equal? Rich people would probably still have more power, right? And more supers would presumably be born anyway later from non-super parents. And that's if there were even enough resources to make gadgets for ALL humans. And what about the Amish, those cannibals on that one island, and other people who would 100% refuse to get gadgets to give them powers?
