Just look at different age groups. Children are isolated forcibly by their parents, so they're not informative. Adolescents, though, take great pains to avoid isolation even though their parents and society generally goes to great lengths to try to impose it upon them. Retired people do not generally isolate themselves (there are, of course, exceptions). It's only the working stiffs that tend to isolate themselves. And even that is mostly a modern phenomenon. It might be down to people being satisfied with social media as their means of socializing, but I doubt it.
Personally I think it’s a crapshoot: your expectation might be true or these workers might become recluse and replace the time commuting with sitting at home (especially if they tend to be in a neighborhood that favours individualism over collectivism, isolation over community).
