AIs are bogged down in bankruptcy and unable to expand territory. From turn 1-145 (Epic Speed, b4 medieval), There are two civs in my game, namely the Ottomans and the Greeks. They don't build their second city and I can see that they are quite bankrupt, suffering at least -10/turn gold. I think that's because they don't know how to guide their trade route and it keeps getting plundered by raging barbarians.
In fact that happens to me very frequently also, but I am smart enough to send troops to guide my trade routes. Also, barbarians are now everywhere using the RB option. Possibly because they tend to wander off away from their nest and even you clear the encampment there are still a few out there preying on your caravans.
