There is this arrogant ugly hubristic conceit displaying in more recent generations, that history is useless, and there is nothing to be learnt from the past, because newer generations know better, and are more moral than all generations preceding them.
Shut up grandpa!
There is nothing we can learn from you. We’re the teacher and you’re the student!
Whenever anyone even dares to admit any nostalgia for any earlier time, they are treated like they don’t *know that time as well as they think they do, and told that not only that things-weren’t-as-good-as-you-think (again implying said nostalgic person is longing for a time that never was, this even if they actually HAD BEEN THERE, but also spelling out how the changes from then to now were not a trade off, (which they actually were) but that ALL changes are IMPROVEMENTS (which is itself a BIAS).
These nostalgia-bashing opinion pieces are tantamount to a kind of modernist supremacy.
* the character of the nostalgic straw man is always painted as someone who never personally saw that time; as someone who only saw a period-era movie, and wants to play dress-up.
