Do we want true equality like that? I certainly don't.

I will be the first to admit I derive a lot of meaning in life from being capable in my domain the being depended on by others to succeed in that domain (where many others can't). I'd argue that a lot of human drive is rooted in exactly this: being depended on by others and the feeling of belonging and purpose that gives.

Flattening the world until we're all equal just means there's no role any of us can uniquely fit, and really no difference between each other at all.
