My grandmother, who lived to 90, used to tell me "The only thing which really improved in my life is medicine." She would tell me that people were so happy and society was so safe when she was a child that her family used to sleep with the windows open.
I also observed things only getting worse in my life. So I really don't buy this narrative that things keep getting better. IMO, the only people who think things got better are billionaires and multi-millionaires; of course it got better for them but it didn't get better for the average-luck person. For the average ambitious person who worked hard to improve their situation, things got MUCH worse; there are all these artificial barriers preventing them from succeeding, depriving them of opportunities and then constant gaslighting to blame them for systemic issues (including their own failure to thrive). Low birth rates, high rates of depression, high rates of homelessness, high suicide rates speak for themselves.
The fact that it all gets covered up by social media echo chambers to the extent that some people think life got better, makes it MUCH, MUCH worse, not better. People just don't seem to notice the tent cities, the increased immigration (due to worsening conditions in poor countries), the political division (again, driven by poverty).
