If you take a look at GDP graphs of eastern europe, russia and the middle east, you will see that every GDP in the region rose dramatically over the period of a few years in the early 2000s. This increase in GDP in the region was not caused by turkey's investment in infrastructure, it was caused by foreign investors (mainly by the US and major players in Europe) trying to bolster their own economy by supporting emerging markets. And it worked. Turkey's istanbul stock market went from 20K to 70K points and foreign investors made a lot of money. There was a period where USD and EUR were on par with the YTL.
When the hot credit finished, Turkey started experiencing inflation again, because not enough of the money was spent on infrastructure.
It was partially spent on better healthcare and education, which won the popular vote for a second time. At this point, government was running on fumes, domestic debt went rampant.
Authoritarianism, nepotism, militarism, conservatism, religiosity, nationalism and xenophobia worked part of the way to support this sort of economy. Seeing success in its ways, and still having some popular support, the government parted ways with its next leader and changed the law to get its leader elected a third time.
At this point there were enough dissenting voices that the mayorship of istanbul was lost in an election. Government forced another election and lost again.
Where are we now? We are at a point where whoever wins, the whole population will lose. Not that different than the 90s, but at least we've got iphones and macbooks.
