Glam principles become ascendant in pop culture during periods when politics moves to the right

Musically, too, glam often seems to hark backward and step forward at the same time. It can't be coincidental that glam principles become ascendant in pop culture during periods when politics moves to the right - the early seventies of Nixon and Heath, the eighties of Reagan and Thatcher, and, most recently, during the first decade of the twenty-first century.

This is a problematic book, and this a problematic statement (I do not believe we can call the early 21st century glam-influenced in any meaningful degree), but I do like it.
