I will bet that, having not read the book, Yanis omits the three main points regarding the Greek Tragedy, as you so eloquently call it.
The first one, the biggee; they should never have been allowed into the EU in the first place.
They did not comply with any of the entrance criteria, and it is doubtful if they have done since.
They managed to con Valerie Giscard D'estaing into campaigning on their behalf under the false premise that if Greece joined, Turkey would never want to.
VGD fell for it hook line and sinker; and who did he turn to, to help Greece cook the books and make it look like they were compliant?
His good friend in London, Margaret, who despatched one of the big accountancy firms to Athens to put the books straight; unfortunately the straightening of the books turned out to be a monumental work of fiction, one that Margaret's big chum, Jeffrey would have been proud of - ordinarily Jeffrey would have lent a hand but he was busy that week end entertaining hookers at his Thameside apartment.
Thatcher was very keen to improve relations with France at the time and thought she could do business with VGD; there were a number of her private notes declassified a while back, they made fascinating reading, particularly the contrast between what was happening in private and the headline grabbing guff being spouted in public.
I'm afraid the Greek people can complain all the like about the EU, but their problems are entirely self inflicted over generations and they just do not have the will to sort it out.
Once the cradle of Democracy now a basket case.
