I don't entirely agree that the problem is reluctance to engage in village reciprocity.
My village is very geographically dispersed now, it's much smaller, and expectations have changed.
My grandparents had minimum 4 siblings each, who between them had an average of 3-4 children (even allowing for a few being childless), all lived within about 5 miles, and the wider network of aunts and cousins was huge (and very local). They knew their neighbours and were part of a community, they would have chatted on the bus, or in a queue at the butchers. My childhood memories included lots of women gossiping about their village, Jean-next-door's son is married to that nice girl from New Street who was the coal man's daughter, no from his second marriage when he married old Mrs Simpsons niece.
Contrast with today. I have one sibling who is equally pressured for time (though we do reciprocal emergency care), our parents spend most of the year abroad, and my in laws are two hours away. My town's high street doesn't have a butcher or greengrocer and my neighbours are all new to my local area and we don't have many shared acquaintances. The daughter from next door, lives 300 miles away.
I could invite lots of people for Christmas dinner, or spend my free time touring the country visiting relatives, but it wouldn't make a village, and it would make my lack of time and head space worse rather than better.
