Germany will always be more advanced than Turkey, in my opinion, unless Turkey undergoes huge socio-political transformations in the coming years.
Firstly, Germany has become a country of immigrants. It can always attract enough immigrants to replace its aging population, compensate for its workforce shortages, etc.
Turkey, on the other hand, is nowhere near becoming a country of immigrants. In the coming years, it'll have to find a way to cleverly tackle its workforce shortages and aging population, not to mention a rising percentage of ethnic Kurds.
Also, no one thinks Turkey's economy will overtake Germany's in the coming decades. I only heard this from you.
Maybe you should study economics a little more.
Turkey is a middle income country with GDP growth in 4-5% range with Germany at 1-2%, a little maths says it wont take long for Turkey to approach Germany.
Being an Arab, you are butt-hurt against Turks due to their centuries of rule over your people naturally.
