psychopath makes a good point. It IS too expensive to raid. I mean maybe caravan raids are profitable, but no one has towns wealthy enough for there to be real returns yet.

The Vikings didn't normally raid broke villages exactly for this reason. Monasteries were the target, and in this case low level manors fill that role. 100 guys burn down a level 0 manor and make off with 1000 bullis. Raiding farmland I see as a means to pay upkeep for an army already raised.
