I marvel at how much was done, and with how little, in bygone days.
I guestimate that the old Eaton County Courthouse has 15,000 square feet of space. It comfortably served a population of 30,000 inhabitants. Eaton County population was essentially static between 1870 (25,000 souls) and 1940 (34,000 souls). That works out to about 0.5 square feet of administrative "burden" for each resident of Eaton County.
Efficiencies gained by computers have been offset by increased court loads in "family" law, DUI and the fact that we have a higher percentage of feral-citizens. Activities that were handled within the family, church or smaller community have been bumped up to the county level. No doubt, "economies of scale" have often been used as a reason for doing so.
It is just one of those things that makes you go, "Hmmm!"
