Could be. I wonder if we could (or if anyone has) poll(ed) people on opinions and, with hindsight, establish an actual truth, or at least the best possible guess at it, and see how different things affect that

I feel like my generation (90s) is a lot better informed than almost any parent, let alone grandparent. But maybe that's too long a scale and you rather mean low tide on the span of the past handful of years, on which I don't really have an opinion / can't really say

This is nonsense.

People are more informed than ever before.

The past looks better only because it is a distorted view from a lack of information at that time.
