I'm just jumping off another thread, where people were describing the 1990s as a golden era. I disagreed with that, because while some things were good about that time, a lot wasn't, and a lot of why we think that things are awful now is because we have 24 hour and instant news on our phones.
I'm reminded of the Woody Allen film Midnight in Paris, in which an American writer from 2010 (when the film was made) finds a sort of time portal into 1920s Paris, which is his ideal era. While there, he meets a beautiful woman whose ideal era is La Belle Epoque, so only 30 years before the '20s. She ends up leaving the '20s to go back to the 1890s, and while he is trying to talk her out of doing so, he has a revelatory realisation that people always idealise the past and look down on the present. It is a form of escapism and a little bit of it is fine, but too much of it stops you living your life to its fullest.
I have seen the film a couple of times, I rewatched it a couple of weeks ago and I found it really resonant and relevant to today's climate. I see a lot of nostalgia about, and while I understand it, I also think that we are in danger of idealising the past as a way of avoiding our day to day issues and doing what we can to improve them. There are a lot of excellent things about today's world that we would miss if we were dropped back thirty or forty years ago.
YANBU. People need to see the past for what it was and stop idealisng it.
YABU. We really are past our best and life is only getting worse.
