What is the cultural difference between Turkey's urban middle-class and rural villagers?

Very difficult to generalise, because up until relatively recent times rural Turkey was extremely diverse. It still is, but there used to be surprisingly large nomadic populations, and there are still farming communities in some places where they retain a form of 'biblical' Greek as their first language! Almost one in five Turks has Kurdish ethnicity, there are also Georgians, Tatars, Azeris, Bulgarians, Circassians, Roma, and many smaller groups. There was little modern infrastructure in the Old Ottoman Empire, the Ottoman Army was said to be the one army which was not required to march in step, as there were few well paved roads. There was little industrialisation outside European Turkey and the large cities, such as Constantinople and Smyrna/Izmir. The Armenian and Aramean/Assyrian populations were previously much larger than they are now
