The thing is that while people struggle harder and harder for a smaller chunk of scraps, they still have a lot of quality of life improvements over the standard of living back in the 70s.
You almost certainly have decent access to passable air conditioning, which was far from a given back then. Even if you can’t afford decent health care, the sporadic health care you can get is still better than the standard of care then. You can have a 60 inch television and more content provided to it than you could imagine… You can instantly engage with people all over the world.
On the scientific discoveries, we have gotten the low hanging fruit. The twentieth century was remarkable, but the limitations of physics are harsh. A lot of excitement as we went from barely pulling off heavier than air flight to a moon landing in under 50 years. Media naturally imagined space exploration to be just a matter of time. Alas everything is exponentially harder and any further loopholes are supremely elusive.
Probably the one area with a great deal of unrealized potential would be biology, because the ethical easy forward is slow.
