Earlier quoted context omitted.
I think what we've shed are more things like chairing a committee for the VFW, selling snacks at little league games, or being active in a lowers voice, looks over shoulder union. These are things that would traditionally take up the social slack left by not punching a clock every day, and we've eliminated them systematically to make room for more marketized activities. Today's retirees are "richer" than their parent…
In what way have we "eliminated them systematically"? Maybe I haven't paid close enough attention, but it feels like those activities have (unfortunately) disappeared largely naturally.
While it's true that there are some positive factors causing it (e.g. housework has been made far easier through inventing/factorying/delivering/installing of appliances like vacuum cleaners, washing machines and dishwashers, and the world has just become easier and safer to be in for women through things such as reliable cars with power steering, mobile phone, and policemen who respond) there are a lot of negative factors that just push those time-rich, more society enriching-capable women into the world of work.
The main one being what I already mentioned: house prices force them to work to pay a bank back for paying a boomer a massive price for a house, to keep up with the other two-income house bids.
