While I have a lot of sympathy for the Occupy The World protesters (if not necessarily all the things they ask for) I find myself feeling exactly the opposite way about the Greek protests. Their economy is a shambles and their country came within a whisker of having to default on their loans, withdraw from the EU, go back to their own currency, and witness catastrophic inflation and massive economic collapse and yet they are violently protesting the very measures that are plugging the holes in the dam.

This isn't peaceful but belligerent demand for change but rather throwing molotov cocktails and gasoline bombs at police. It is true that they have plenty to be angry about as their government is taking away money and rights that the Greeks thought they had for life and there is a very justified perception that the rich countries of France and Germany are the driving force behind these unpleasant changes. That said, there is no logical basis for this protest. At least the Occupy protesters are getting attention, being nonviolent and have achievable goals - the Greek protests are utterly hopeless. What could they possibly get that would satisfy them aside from the rest of Europe pouring more and more money in an endless upward spiral into Greece? They already know that down that road lies isolation and disaster as the EU will not put up with it.
So now they scream and shout and loot and burn and shut down the country for days to tell the government that instead of austerity they want catastrophe. The demands that the government continue to pay out as it has always done are an impossibility; there is no way in which that can occur. The solution now is to get the government to act quickly to resolve the situation as best it can and work to try to rebuild. Here we have a disastrous example of fear of loss destroying any rational attempt at a solution. The people of Greece fear losing their benefits and they fear a collapse but there is no appropriate weighting of those two things. They are rushing into a burning building to recover a wallet left behind in a dresser drawer and they don't seem to see that the building is going to collapse long before they can get out again.
