The problem is that this gives a false view.

Look at Germany and France. Most of the poor EU countries that are on the brink of collapse because they owe far more money than they could possibly ever pay back... called the PIGS... Portugal, Italy, Greece, Spain... or is the I Ireland??? Whatever... the point is that all that owed money is owed mostly to France and Germany so they aren't nearly as wealthy as they pretend because they have lent money and likely wont be getting it back any time soon... which means it really doesn't exist...
