To impart the towns and cities with a greater sense of life, Bethesda has populated them with mills, farms, and mines that give the NPCs believable tasks to occupy their day
Yes! that's what we wanted. An end to the aimlessness. It felt real in Morrowind because everybody was always at their tasks, so the illusion of movement was there. In Oblivion, you saw the real time banolity of NPC existence, and the way only about 20% of the population had jobs. All the mines were unused and full of angry skeletons, the economy was roughly on a par with that of Ireland during the potato blight.
Hopefully this will change in Skyrim.
