Tim,
These predictors of Goldman Sachs and others, did not predict the current financial crisis even though they were involved and dealing with sub prime mortgages all day every day for years. So I do not doubt their political neutrality, just their overall competence. If I remember rightly, the same "experts" were predicting that by the end of this year Greece would be in dire straits and Greeks would be leaving the country in droves to work overseas. Instead, the USA almost went bust.
The rise of the Turkish economy has been touted for years. I remember interviewing chaps from International Harvester in the 70s and they too were counting on Turkey being a better longer term growth market than the whole of the Gulf. They could see more construction in Turkey, which has yet to exceed that of the Gulf.
If the per capita income in Turkey will be 60 000 USD by 2050, how much will it be in other nations like Germany and Sweden?
Looking at the pattern in Turkey, what is visible is a course like Spain. The Spaniards started as a center of cheap copies, made in locally owned firms, ie Seat. They then moved on to copies made by foreign owned firms, ie Opel made in Spain, to a modest level of innovation which in no way competes with the real innovators. The model of the cheap manufacturing center for foreign designed goods is unilikely to change without local grown innovation and technology.
