they don't necessarily understand? >> it depends what side you're on. on the yes side if you want to say yes to the creditors' terms, what you think you're voting for is to stay in the eurozone. if you're on the no side you're agreeing with the government's strategy which the government is saying if you say no that's going to empower us give us a mandate to go back to the creditors and say -- hash out a deal that will keep us in the euro but on better terms. those that believe that are inclined to vote no. those that believe that a no vote would endanger the euro are going to vote yes. >> what's better for greece? >> in my opinion a euro exit would bring total chaos in greece. it would only show all kinds of political and social turmoil. over the long run the advantage for greece would be it would devalue its currency and make it more competitive in a global economy.
