By chance I grew up in a place which used to have a post office. It was a "fourth class post office". You've never heard of such a thing? They used to have them back in the late 1800's, but it was closed before the turn of the century. So instead we were served by a rural delivery route out of a post office 3 miles away, in the same small town which housed the central school. "Central" because it represented the results of consolidating a bunch of one-room school houses into one school system.
My point is simply that the consolidation and centralization of facilities and infrastructure is not a new thing. See this Rural Blog post on the current go-round.
