Why is inequality undesirable? This is something I've always been confused about

No it hasn't. Capitalism and its workings are relatively recent. Capitalism is an improvement from feudalism, but humans can do better.

...

I really don't know I'm asking for here. I believe that inequality is bad in itself, yet I cant logically convince myself that is indeed true. Perhaps I really am asking for some stupid metaphysical explanation so that I can keep believing what I do

What did you expect? It's a bait thread.

Morality isn't founded in logic m8.

...

Inequality has existed since the dawn of civilization

Its not.

Explain.

There is no such thing as good or bad. Morality is subjective, and completely decided upon in the mind of the person. It is a spook.

I know. That's why I don't accept the arguments against inequality that appeal to morality.

So basically, there is no objective reason inequality is undesirable except the possibility of the exploited fighting back ?
