Yes. All of those were indeed miserable places to be if you were poor or did not have right skin color etc. I agree.

> You actually need to make a moral argument. For example, slavery is bad not because it caused the the Civil War, but because it's morally wrong (and there's plenty of arguments here)

No necessarily. I'd prefer to make an utilitarian argument. Over long periods of time high inequality leads to inefficiency due to wealth accumulation across different generations.

I could try and make more arguments, but I'll let you have a go this time..
