Who cares about Greece, after all, what is their contribution to the world economy... yeah, thought so.
Besides, Lehmans profits were probably greater than Greece, Portugal, and Spain's combined GDP.
Honestly, if Greece default, life will go on. Many countries have defaulted before and they are the only ones who suffer the most. The economy finds a way to isolate itself from them, always has, always will.
Welcome to globalisation man. There are just too many variables and too many players chomping at the bits to pick up where Greece slacks off.
