What else about this chart?

That is some damn good measuring of the differences in yields among European nations. You know, if the Dollar could measure with the same precision, the differences between the Great Lakes and the Southwest, then inventory management would yield efficiencies.  The  precise, easy to use currency survives, why not say that the Euro is not in  trouble, but the Euro is providing great utility.  The Dollar is in trouble, the Dollar in trouble because it role as a global currency masks its domestic precision, we suffer information loss.

What does this chart tell Europeans?

Been there, done that. They get it, they are realizing their write offs, shortening supply lines, and from  will now accumulate new inventory and grow new wealth.
