The Kurds I've met are all from the larger cities so I can't speak to rural concerns. It's not all roses:growing inflation, a growing wealth gap, violence in Kirkuk and Mosul (both in or out of Kurdistan depending on your being a Kurd or an Arab) and in Arbil the strong hint of a cult of personality with the Barzani and in Suly Talibani. One businessman the other day told me he was happy to buy fuel for his generators and all his water as long as there was no fighting. My sense is that is common opinion and the failings of the KRG to provide utilities are a distint secondary concern to security.
