Reminder that everything was better in the past. Prior to WW1 you could travel around most of Europe without even a passport too.
And much before that there were no passports. Maybe you have a point. Say Columbus et cetera :D
Apart from medicine, travel speeds, cost of travel, life expectancy, hot showers, central heating, cars, dentistry, sanitation, civil rights, and fewer childbirth deaths... you're absolutely right
Everything but lifespan I think. So Expected Value of life remains flat over time.
Well, I can travel around most of Europe without a passport right now? ID card will do just fine, even though, really, nobody ever asks me for that either.
Meanwhile, my life expectancy is, like at least twice that 'prior to WW1' and my disposable income at least 20 times my take-home pay in 1917.
Bloody EU, innit...
