Except that if Rich published statistics, I think that you'll find a
majority of income comes from trade, not garrisons. Once you run out
of land, it's fairly expensive to build enough structures to increase
your income. The game, as it stands, emphasizes trade a bit too much,
in my opinion. You probably don't agree, but that's OK with me.
