in the UK most villages/small towns without a school have very old residents with no real village population replacement (people die of old age and the big old cold houses are bought by increasingly wealthy retirees leaving urban environments). The current residents need increasing amounts of care and infrastructure but there isn't anybody nearby of working age (compounded by the fact that NIMBY policies have driven village houses to unobtainable prices for average families and rentals are usually very rare).

more of a socio-economic observation but it's a problem that needs solving for each village - the current solution is government subsidy from urban areas to pay for care workers and pharmacy to drive around all day in the countryside to see people for a few mins each

I'm thinking if each rich old person in the village paid a subscription for a dedicated local care team who lived together in a nice house in the village (like 30x people paying £1000 a month to support 5 people) then that would be a balance for a very decent care wage + consistent high quality care
