Well, I think it indeed a problem of the greek society, not only just the government.
Faulty payments, Rip-offs (regarding pension to people who dies years ago, or remember that village with 80% being blind to gain extra funds, etc.) and the low morality to pay taxes have worsened things a lot...
I dont believe that all the erfforts will be enough, since the greek People will refuse to follow the new laws that save money.. I would too probably. Your anger about the hdd is just One small Part of it.
If greece declares itself insolvent, all debts would be resetted. Now whos to blame then? Other countries such as portugal, spain, italy may watch the ongoing Development with much interest.
Myself, I wouldnt invest a penny into any stocks or assurances anymore. Estate may be the safest bet so far...
