A DEBT OF A "GAZILLION" OR ANY OTHER WORD USED.
It is logical to establish a country as "poor" or "bankrupt", if its debt is of a GAZILLION or more ! That is, that its debt is bigger than "printed money can pay"...!
A real killing debt,would be greater than this Gazillion, in which there would be not even resources or production means to produce "monetary gain".
But if this "poor" country could legally, have its own "money printing machines", and "their own production of "money paper", and low wages and costs. It is "illogical" to determine this country as "poor". Even if they do not have much GDP, or few ways of production and resources.
So the WORLD of the rich countries control, or try to control their power, over the poor countries, printing the money for the "poor" countries, so that it be "legal tender".
