The whole world was changing and this confused Hubert Bonisseur de La Bath, who even though he thought he was hip and with it, was just hanging on the last remaining thread of the way things used to be. He didn't fit into this new way of life and he couldn't figure it out.
Hubert was a reminder of how things used to be, while his companion, Dolores, stands as a beacon of what society is becoming and how some ideologies need to find a means to an end.
Hubert and Dolores are both ends of the spectrum and neither completely show a perfect picture of society, but they do show how things change and how new things take those places left behind.
