Why did so many Turks in Germany vote 'Yes' in Erdogan's referendum?

This is a follow-up to this post.

The Swiss newspaper NZZ has a good article on this. Here is an excerpt with some numbers as to how Turks living in Germany are integrated compared to Germans. Keep in mind, that the ensuing tenor on the internet and in the papers after the results came out was that Yes voters would best leave (that was one of the politest terms) Germany if they were really so fond of dictatorship. With that in mind, let's turn to the NZZ article (Google translate):

Two thirds without qualification

In Germany there are currently 2.9 million people with a Turkish background, 1.4 million of which are entitled to vote. Of these, half voted for the vote. If green and left-wing politicians now demand greater integration, this is a late insight. In Germany it was a long time before, and the Turkish migrant workers would return to their home country. However, when they were able to catch up with women and children from 1974 onwards, the work became family migration. Only the Immigration Act of 2005 brought a legal anchoring of measures for integration in Germany. This has worked poorly for Turkish citizens. In their life situation, they still have a lot of catching up to do with the locals and also with other immigrant groups. According to the Social Report 2016, 65% of the persons with Turkish origin do not have a vocational qualification from the Federal Center for Civic Education and 72% for women.

Certainly there is progress from generation to generation. Among the 17 to 45-year-olds, 41% of the Turkish nationals have learned a profession and 8% have completed their studies. But if this is compared with "natives", the difference remains striking: 17% of this age group is without a vocational qualification (many of whom are still allowed to study), but in those with Turkish roots every second one.

It is not surprising that 42% of Turkish nationals are unskilled or semi-skilled, while it is only 12% of the "natives". The income of Turkish households is correspondingly low. 36% are considered to be "poverty-stricken" (they have less than 60% of average income) compared to 14% for people without a migration background.

According to a study by the Federal Office for Migration and Refugees from 2010, which only takes people with a Turkish passport, 54% of Turkish men in Germany have experienced unemployment. It is true that most Turks have enough knowledge of the German language to get along. An exception is the study of 35- to 64-year-old Turkish women, of whom 38% spoke badly or very badly German. This also fits into the fact that every third Turk has no contact with German friends or only rarely.
