There has always been a market for nostalgia. Some of it is due to each person, other than those who had traumatic experiences, looking back on their childhoods with rose-tined glasses. Some commentators, especially right wing ones, alarmed by the progressive changes that are taking place in terms of greater equality for marginalized groups, have seized upon that tendency to proclaim that things have deteriorated from some prior golden age. They seem to have fixated on the 1950s as the high point in US history, completely ignoring the fact that it was not a good time time for anyone other than middle-class white cis people.
Currently, there are doomsayers who try to convince the public of this by picking on some cultural features and complaining that people no longer have a work ethic, have become hypersensitive and lost their sense of humor, and that men have become less manly. These fears are reinforced by the echo chambers of social media, and that constant repetition may convince some that these things are really true.
