Here's my theory. We support competition in almost every aspect of life, while demanding equality, thus PROJECTING inequality. Its like we're in a state of mass cognitive dissonance where we feel like we can live in a world where we rank people and support the art of competition, yet also live in a world where we're seen as equal. (not necessarily as minorities but in gender roles and any other way that anyone can be shat on for something)
My solution? Inequality goes as soon as competition goes.
