A global view is probably not the right way to look at things, encouraging as it may be. Of course globally hunger rates fell and so did child mortality. If nothing else, by the inexorable progress of science and technology.
But what about comparing the same country/region? After all that's a better sense of how things are progressing locally to you, and when people are asked "are things better or worse" they probably compare the way they live with the way their parents lived.
Would you rather be born in 1980 or 2020 in China? In Poland? No question. Same question but in the USA? In the UK? The West in general? I'm really not so sure.
As an American with severe hemophilia, 2020, without a doubt.
I was born in 1978, and in the early '80s, beat approximately 50/50 odds by not getting infected with HIV from the only available treatments at the time, and as a result of this and other risks including hepatitis, treatments were only used in response to active bleeding episodes throughout my childhood, resulting in arthritis in my ankles and elbows by the time I was around 8.
And I still wound up with hepatitis C from near birth (at which point it was referred to as "non-A, non-B", as the virus would not be identified until the late '80s) until a cure was developed decades later, fortunately never symptomatic.
So, while I beat the odds, my life expectancy from birth until much later would have been considerably longer had I been born in 2020, and my joints would work a lot better.
Oh, and as someone who grew up with the Shuttle and attended both Space Camp and Space Academy in Huntsville, inevitable political nonsense notwithstanding, I'm elated about the successful mission.
As for the odds, given the opportunity, I wouldn't even hesitate unless they were worse than 1 in 10.
