More like the capitalists don't dare let them succeed. It would show the world that there was another way, and demands to go that way would escalate in other states.
I will assume that you are not a troll. The fault lies within the Greeks themselves. You cannot forever consume more than you produce. No matter who you are. Capitalist or socialist. Greece has borrowed to support their lifestyle since WWII, if not before. They are constantly running an operating deficit. Nobody wants to lend Greece money because Greece does not want to change their ways. They want to consume more than they produce. The Greeks would't lend themselves the money!
Austerity is not the problem, it's a solution. Did you Notice that Greece has not proposed one solution in which they pay back the debt? They only demand they are bringing to the table is that they can't be asked to reduce their spending. It's humiliating.
Now some will come forward and say that a recession is not the time to reduce spending. This is right when you are not always running a deficit and when the burden of your debt is manageable. Greece was forgiven 100 billion euros already. If the Greeks don't want the austerity measures let them propose a solution to the repayment of all the loans including the 100 billion which was forgiven on the condition of austerity.
I am more of a socialist than a capitalist. I honestly believe that the state needs to help even the field in order to produce more than is consumed which translates to building wealth. Yeah I agree with you the boogieman did it. It's just that the boogieman in this case it's the Greeks who think that they are entitled to live beyond their means.
