Could this, in part, be behind some of the bump for slogans like "Make America Great Again" by looking back to an imagined past?

laudator temporis acti translates as "a praiser of times past"

Calls to mind:

Multa senem circumveniunt incommoda, vel quod quaerit et inventis miser abstinet ac timet uti, vel quod res omnis timide gelideque ministrat, dilator, spe longus, iners avidusque futuri, difficilis, querulus, laudator temporis acti se puero, castigator censorque minorum. —Horace's Ars Poetica (line 173)

Many ills encompass an old man, whether because he seeks gain, and then miserably holds aloof from his store and fears to use it, or because, in all that he does, he lacks fire and courage, is dilatory and slow to form hopes, is sluggish and greedy of a longer life, peevish, surly, given to praising the days he spent as a boy, and to reproving and condemning the young. (tr. H. Rushton Fairclough)

In Horace's version he's talking about a old curmudgeon and the phrase often has a pejorative tinge. It generally is used to mean someone who defends earlier periods of history ("the good old days") usually prior to their own lives and which they haven't directly experienced, as better than the present.

Compare this with the sentiment behind Donald J. Trump's "Make America Great Again". - https://en.wikipedia.org/wiki/Make_America_Great_Again

The end of the passage also has historical precedent and hints of "You kids get off my lawn!" https://en.wikipedia.org/wiki/You_kids_get_off_my_lawn!
