I think he's saying the whole song is meant as a criticism of the 60s counterculture and mourning the end of 50s America, and today's "wokism" is just an extension of the various sixties movements. He's nostalgic about driving his truck down to the sock hop with a pink carnation in his suit and then going down to drink with the "good ol' boys" at the levee. Now Lenin (Lennon) is reading Marx and everything is just too damn political! He directly calls out a bunch of the classic 60s counterculture songs.
