Greek Euro Exit Would Be Worse Than Lehman

Maybe Iâ??m wrong, but every time I look at the possibility of a Greek exit right now I see it spiraling out of control and dragging down the entire global economy. I hear and read the arguments of why it's controllable and they just donâ??t seem credible. Pundits tend to link a Greek devaluation to other devaluations that have little, if anything in common. They also seem to ignore human nature and how the markets will likely respond.  I think with planning and time, a Greek exit would be manageable, but right now it would create chaos, first within Europe and then the globe.
