It captures so much of the essence of the relationship. With small debt, a person or a corporation or a government can generally work something out. Skip some unnecessary spending, scale back a bit, and things all work out.
But debt chokes off options. Too much debt, and growth stalls. It's a really vicious circle. If we upgrade the factory machines, we can sell more, but we can't afford to. If we move closer to work, we'd save some expenses, but we can't afford to. Opportunity becomes rare, and it's demoralizing.
I totally understand creditors need their money back. Presumably there was something magical about Greece, some golden egg it was producing that enticed the lenders. I don't see how they can get their money back without killing the goose though.
