I agree with you in that Greece's debt does need to be substantially restructured because it's unsustainable. I just think the whole "setting of precedence" is what's keeping us fixed in the same place.
I don't believe that it sets any sort of precedence where everyone in the union can just not pay their debts. In society, we allow people to negotiate debt repayments in a way that isn't harmful to them and their families. People who can pay their debts and don't need this facility do so. That is the only precedent we should look at: if debt is unsustainable for individuals they are given the opportunity to restructure repayments in a way that is affordable to them without detriment to their life.
In Greece, this isn't what's happening. We see relentless spending cuts, stupidly high unemployment and a group of people who know what to do but are being told they can't do it.
That and I don't downvote based on something I don't agree with, I just wanted you to know I didn't downvote even though I don't agree with that approach, as much as I really want to. I use downvoting on comments without substance, especially ones that are overtly negative without substance.
