They're much more stable, they're not mired by brutal crackdowns on minorities and they're highly developed. They're not going to collapse by the time oil is obsolete (which is ridiculously far away) that's just fear mongering and their strategic importance hasn't waned. They're significantly better off by a large margin. The biggest problem is they rely on exploiting expats and won't grant citizenship because it'll take away their welfare state. It's not developed on "paper" it's actually developed.
Attaturk instilled ultra-nationalism and unity in his nation, it may of not been great for minorities but unity, education and industrialisation was what pushed his country along.
An autocratic police state is truly the best form of government. Whether it be the UAE, Rwanda, Singapore or China. Attatruk was a moron for even attempting to pivot it to a democracy.
How do they treat their minorities? horribly! ask the maids how they are treated, ask religious minorities how they are treated.
Saudi Arabia is collecting more taxes now because the system isn't working, their dollar reserves are collapsing, their GDP isn't going up anymore. Search it up and you'll see that since 2015 it's not going well.
I do not agree with everything Ataturk did, pushing etho-nationalism on kurds wasn't a good idea but the result 100 years after the turkish republic was formed speaks for itself.
Believe, you are clearly better off in free democratic countries.
UAE relies on expats.
Rwanda is a poor country.
People are leaving China so that they can go to the US.
And Singapore isn't really a country, it's just a city.
Clearly Democracy is better than a dictatorship.
