Can Humans ever be Truly equal?

If all humans were equal then that would mean that we all think alike and the same things are exspected of us. That no body would be better than anyone else or everyone would be the same if we were all equal. The world would I think turn into every single little thing would be the same like houses, cloths, cars, and schudeles even. Like for example if you even seen "The Cat in the Hat" everything about the people apperence is the same like their cloths, houses same color and shape, same cars, and just everything. That's what I think if everyone was equal in the world.
