What was the typical job? What was life expectancy? How warm was a typical home in the winter? How many books did an average person see (much less, read) in the lives? What was travel like?
Also wealth disparity is a stupid metric. If you and I are homeless under the bridge, it does me no good that we are equal. If I have a house and you have an even nicer house, I am fine. (though I'd rather have the nicer house)
I hear people who are pro-capitalism say “the poorest people in the US have it better than kings did 500 years ago”, which is only true if you’re considering the stuff those people have. If you’re considering the ability to self-actualize it’s not at all true.
I don’t think things are worse now than ever before, but that doesn’t excuse the concentration of power we have today.
What does that mean? 500 years ago, did one have ability to speak to like-minded people globally? Could they travel as they wish? Could they pick their religion? Could they choose where to live? Could they pick a wife from another culture? Could they read about any topic they want? Did they have a shot at starting a business and having it grow into real wealth?
If you think you are more powerless than a serf 500 years ago because Bezos has more money then you, then you are the one who gave away your power for no reason
