Greece is a welfare state, they cannot live within their means, they refuse to.
They haven't any need to do so, their system doesn't require that they do... so they don't... never have... and why they are where they are now. It's a culture of privileged entitlements.
Voting isn't going to change their situation...it just gives the President more leverage if the EU continues to do so, and the creditors agree to "terms".....which of course won't be met either over time.
Many 'think' by voting they will have their money and life back...
The people pretended to worship their god, the state, and the state pretended to bless the people. Their god has feet of clay.
Greece is hardly alone
