I don't necessarily disagree with your sentiment but I think at this point it is good to take a step back and consider the magnitude of the statement you just made.

Consider the extent of human societies that have existed, what it is that we know of them and through what lens we know of them. What do we mean by the words "significantly worse"? Where does this idea of "worse" stem from? And let's not forget the average person. How do we measure what's good for this average person?

Sorry for the random remarks your comment caught my eye for some reason. The point here isn't for some bogus relativism but merely to state the obvious, that the human condition can be far more complicated than we give it credit.
