It does not seem a good idea to hold a referendum on paper (here in Italy it seems that it costs at least 400 million euro, some people say 800 million, the truth will never be known) for groped to solve the economic problems of a country.
When the "democratic" Nations will decide to create a system to ask citizens their "opinions" (decisions would be better) via internet and therefore this can be done once or several times per month, we will get closer to a "real democracy" (for the moment it is false).
Good luck, Greece!
[P.S. Nations have not lost time when they have implemented POS !!! ]
I think, however, that Greece should give a good kick to Europe.
This Europe serves only to Germany (to other countries only to fill the trouble).
Italy needs to shoulder all the burden of millions of people who flee from wars and hunger, without any help from the Greater Europe!
I am for a world without borders, but I start to think that I would close our borders... no, not to immigrants, to all non italian products and to European directives.
