Yeah I agree that is incorrect but I disagree to that reading.
Just use logic. If a nation is compromised by systemic corruption what do you think will happen? I believe corruption is like cancer in that it will seek to plunder anything in a non-discriminating manner. All the wealth of a state is up for grabs. What do you think will happen to money allocated for infrastructure and services for the average (weak) citizen? Roads, hospitals, services, etc? Do you think the corrupt ruler and the cronies that enable him will resist the temptation to rob these endeavors? If the cronies rob, do you think the ruling authority will a) look the other way or b) prosecute the crony and risk a backlash?
To an observer who has visited Turkey several times both before and after Erdogan, the difference in improvements is literally night and day. Simple example: before, one couldn't even receive proper medical attention (and it would literally bankrupt you if you did). After: health care is a free service and the country has way more hospitals than ever before.
"Corrupt countries often have poor services. Turkey does not have poor services, therefor it is not corrupt."
But surely that's incorrect.
