"Are any of the populace there willing to sacrifice anything for their
country as a whole or is it another 'cut anybody but me' mentality"
That's a hard one to answer without giving maybe the wrong answer, but unintentionally. I'll give you one example of interaction between the people and the govt. There is a high tax on any home once it's been completed, therefore many Greek homes are never completed, always in some very visible state of continuing construction, especially true on Crete it seemed, less so in Athens proper. Of course it was to avoid the tax. They could stretch this out for years and years, thereby avoiding the high tax that would be due. The Greek govt, at that time, rather than lowering the tax and making it more advantageous to just pay the tax and be done with it, instead just left it as they'd set it. The end result of course was entire areas that looked like the contractor walked away never completing the work. The most common look would be the first story completed and a pillar or two on the second floor (which was actually the roof) and when the tax authorities would come out and make enough problem, they'd have another support column poured, to show they were still working on the house, but it wasn't completed yet.
This is their approach to such matters. Europe is all hot and bothered to get a deal completed. Greeks mostly would have no problem letting it slide as long as they could until they get what they want or find some other way around it.
