Ottomans were good for a while but the last couple of centuries were bad. We should be proud of our ancestors and learn from their mistakes such as too many wars which resulted in less economic productivity and reliance on money from victories, wars resulted in debt, debt resulted in inflation, inflation lead to more corruption, and corruption leads to everything else that can go wrong. Obviously the governments monarchy system didn't work, I think 1 sultan was retarded or something, also they had to worry about keeping the family in power. Lack of industry was another and always hiring foreigners to do stuff. Those are the bad sides but obviously we can learn from their successes as well. So or so they lasted 600+ years the longest any turkic empire has lasted and they were probably the most powerful turkic empire when looking at all fields.
There are still Ottomans in europe today such as bosnians, muslim bulgarians, albanians, muslim macedonians, turkish cypriots etc. so that is a bonus for modern day Turkey. The Ottomans are an inspiration for anatolian Turks and Balkan muslims because it gives you confidence in yourself. You can say if they did it I can do it. This brings me to the point of neo ottomanism. Neo ottomanism in my view is the belief that Turkey can become something bigger than what it is today and actually have some influence on external events and have other countries especially neighboring countries under Turkeys influence. It doesn't mean that Turkish armies will be marching across the middle east and balkans again, press tv, assad, and others like to make it seem like that. Neo Ottomanism or just Ottomanism is a metaphor not something to be taken literally.
With regard to the Ottoman family, they have been living outside of Turkey for years so obviously they will end up in this situation, im not saying all of them. Also they have been mixing with europeans since the beginning of the empire.
