The quote reflects a deep sense of frustration with the complacency and stagnation observed in society. The speaker suggests that the nation has become apathetic, resembling "smug contented cows" rather than engaged and passionate individuals. This observation implies that a significant, transformative event is necessary to awaken people from their indifference and to inspire them to reconnect with their humanity.
