Turkic world is probably more appealing to most Kazakhs
Turks are not at all popular in Kazakhstan. Only Arabs and Chinese are hated more.
Arabs because of all the Salafi/Wahhabist influence in the 90s and early 2000s - primarily financed by Saudis and Qataris.
Chinese because they hire only their own, even when they invest - and they are historic enemies of all the steppe nomads.
Turks are a little bit of a different story. They invested heavily throughout the 90s and early 2000s. The first shopping malls (Ramstore), the first consumer goods (Beko), and the first foreign higher education institutions were Turkish (mainly Gülenist).
The reason Kazakhs dislike Turks is because they treat them as the "little brother", dress like gays, and act very vulgarly towards local women. Kazakhs view the Turks as "those that left", and think they should be the "older brother".
The Turks are not even Turks. They are more Greek and Armenian than Turks. Where else can you find blonde and blue eyed Turkic people?
Ever seen a photo of Mustafa Kemal?
