@hawkeye10,
I believe that, taken together, the core issues Greece faces don't permit any solutions without grave political and economic risks. The austerity being imposed by their lenders risks serious short term recession in an already depresed economy. Continued borrowing (if it was even possible) risks evading the structural reforms sorely needed to restore economic productivity. The Greek (and southern & central European) demographic deficit and associated aging population adds to future government spending requirements, and makes short term economic recovery more difficult - adding significantly to both problems.
In short Greece is in a very bad corner with no pleasant exits available, short of a generous benefactor willing to sustain lifestyles well beyond their present means. It is fairly clear now that there is no such benefactor.
The United States also faces these contradictory problems, though happily to lesser degrees. We too appear to be unwilling to face the constraints that high levels of debt and current deficits put on our ability to stimulate economic activity, in the short term through government spending, and on the equally urgent necessity we face of seriously dealing with long-term entitlement spending levels in a way that will not further degrade economic growth. Unhappily our political leaders are merely talking at each other, while the Administration in power continues emphasizing short-term economic stimulation and sustained economic rewards for their constituents , without any serious effort to curtail long-term deficits. This is very likely a close approximation of the formula the Greeks used to get to where they are now.
