I know of a Turkish man who has a council property for his English family, yes he has another family in Turkey. Once he got his council house he then bought for cash, a house for his english family. They moved in to their new house. He kept the council house to rent out to his Turkish employees, who were crammed in like sardines. He isn't paying interest or rent on the private dwelling. He is however raking it in on the rent from his employees. He owns dozens of fast food outlets and has a very large import/export business and runs several very large businesses in Turkey. I think this is the type of person the writer was thinking of when having their rant.
Before anyone says "have you told the authorities". the answer is no. I have spent my life doing that sort of thing and always, without exception, been dropped in it and not supported.
That is why the writer is correct in suggesting the authorities should stop burying their heads in the sand and do something about it. Oh! I forgot, it's not their money they are wasting is it. No chance of anything being done then I guess. As usual.
