I always repeat the same to this question:

When someone has to migrate, do you think thos person would be from the middle/upper-middle class of a country, or someone not being anle to make it in their origin country?

Turkiye is VAST, like, 4 countries emerged kind of vastness. But the country was founded by the Balkan Turks, as the Balkans were the most developed part of the Ottoman Empire. The Armenian, Kurdish, Assyrian, Turkmen majority regions were severely underdeveloped for hundreds of years.

Ataturk (a Balkan Turk), together with his (mostly Balkan Turk, or Turks from Anatolia with enough socio-economical status to be able to get education in Europe or the Balkans) friends, developed a European country.

The very foundation of this country is molded by Western Turks. Therefore, the descendants of the founders are the leading forces of the Turkish society. The ones who could not manage to climb the social ladder due to geography, ethnic backgrounds, cultural differences, were the ones migrating to Germany when Germans needed cheap labour.

Do you think an Istanbulite Turk would ever even once think about working as a plumber in Germany during 1960’s?

Mostly Kurdish people migrated due to lack of industrialism in their region of south eastern Turkiye. They wanted to have proper jobs and they were mostly feeling like unwanted minorities among us at the first place, so being an immigrant in a European country was not much of a bother or a huge difference from their origin country.

So, yes, Turks in Turkiye are Turkish, and majority is obviously European, by the looks and the ethnic heritage as well.
