For a dream that is depressingly minor! How about people stop buying things they don't need. Lost crafts of fixing things are thriving again. As result, elderly are re-introduced into society as they have the lost knowledge. Deurbanization starts when people discover they can't grow their own food on concrete. The 9-5 day slowly shifts back to a dynamic sunrise-to-sunset schedule. Cars are banned from small communities because emission degrades the local crops. As a result, kids rediscover they can safely play outside, without the limiting supervision of adults. That starts a positive feedback loop that collapses the (a)social networks, and as a byproduct the whole economy of attention.
