I'm 37 and a factor that I haven't seen much discussed is that in-office is a vastly higher burden for my generation. Commutes are longer, more families have two working parents (and need to, to pay the bills).
In-office doesn't mean heading out the door at 8:30 and coming home at 5:30 but something more like leaving at 7:00am, dropping off kids at before-school daycare ($$$), driving back to the train station to make it in by 9 and then coming home at 6 after your 1-hour commute to the closest affordable suburb. An 11-hour day, and you are paying out the nose for childcare if you can even get it, and you'll spend all your PTO on kids doctor appointments and parent-teacher conferences and the like.
