Attempts to export its excess savings can only lead to one of three outcomes: A) global growth rises because Europe's savings are all directed at developing countries with
significant infrastructure investment needs and insufficient capital, B) global growth drops sharply, global unemployment rises, and China's adjustment

wave of sovereign defaults.

waves could do a huge amount of damage within a short time (
significant factor in WW2).
