Are the author's observations really representative of a generational difference? When I was younger, my attitude would have been "work hard and party hard", which was a commitment to an active rather than relaxed work-life balance. Among my fellow students, I could observe a whole spectrum from "work hard" to "party hard". My own current anecdotal evidence with young adults from my extended family still includes examples of both. Therefore, I am not sure if the average has really shifted.
