I doubt many members of the generation that came of age during the Depression or WWII would agree that the the rock era was any cultural pinnacle.
I hesitate to use 'never' because it is a very long time and who knows....but, based upon all of recorded history to date I think the "Rock Era", complete with all the variations within it, expanded the quality of popular music moreso than at any time previously. And given the way popular music has gone since the early 80's I would say the chances are very good that the era won't be topped any time in the near future.
And I don't think anyone has stated that we reached any sort of "cultural pinnacle" from the 50's through the early 80's. What was said was that the music of those days had an impact on our culture (and that of a major part of the world) previously unknown. Cultural changes were also prevalent but perhaps not to the extent of those caused by the Great Depression.
Aside from war activities and the baby boom afterwards, music itself did very little to change our culture. What did change it was the disruption of the male population going off to war and the FHA programs upon their return which allowed an entire generation to become middle class home owners for the first time. My family was part of that. The culture of those post-war families began to change considerably during the mid to late 50's and wholesale changes were extant in the 60's.

Most of them viewed the Beatles or Elvis the same way you see Lady Gaga or Pitbull. "Kids these days, why can't they listen to good music with a melody?".
Elvis burst on the stage not unlike other flashy country performers of the day. His major difference was the notoriety he got by the dance moves which was unusual for the time. I don't remember my grandparents commenting on Elvis but I do remember my father doing a bad imitation with his guitar. Both my parents thought Elvis was just 'Hollywood' and didn't have too much to say one way or the other.
The Beatles were a foreign oddity with long hair, thin lapels and pegged pants and they captivated the teen girls. Their early stuff was basic but they quickly improved and put out some great music. Again, they were teen idols but they were not alone. My sisters went wacky over the group but I don't remember my folks saying much, if anything. I do remember some negative comments when a photo of the Rolling Stones appeared in the local paper.

Likewise most teens today likely see 60s music as a quaint relic of their (grand)parents' generation.
I really doubt most modern teens know what "quaint relics" are. I do know from personal experience that teens are more familiar with those Oldies than we suspect because a lot of them have been used in movies and commercials. My 20-something daughter constantly surprises me by knowing the lyrics to some of those Oldies and she was raised in Romania until the age of 15.
