Maybe we should talk about Rawl’s veil of ignorance [1]. If you did not know where you would be born or in what socio-economic class, what time period would you want to live in? Because it’s clear to me living in a 3rd world country (and, formerly, America), that the best time to be alive is now, in aggregate. If you could decide, maybe it would be great to be a king in the Middle Ages, or whatever. But if you didn’t have that choice and instead you randomly became someone, I think most people would agree that today is the best it’s ever been. Empirical statistics back this up as well.
