I mean, when you start out, every fort, mine and cave in cyrodiil is controlled by bandits and such, there's a full blown civil war going on, etc. The economy should be in shambles. As you start clearing out mines, so they can re-open, purging bandits and necromancers from their lairs, the land should get more peaceful and the economy should improve.
If you choose a side in the civil war, arguably the economy might get a bit worse, as you kill off lots of enemy soldiers (which means they aren't around to buy goods and services or have the legion buy those goods and services on their behalf; some of them might have only been militiamen - that is, they have "day jobs", but once dead, can no longer tend their farm or forge, or whatever.
Still, one of the things which inevitably happens in Elder Scrolls games is you bring back all this fat loot from your adventures, and sell it for a fraction of what it's worth to greedy bastard merchants. How could they possibly NOT get rich, buying all that bargain loot and selling it for 2-3X what they bought it for?
