@spendius,
What I want to know is where all these hundreds of billions were kept before being used for the bail outs if it wasn't in the very banks having them pumped in.
Maybe the invention of double-entry book-keeping is the real culprit: thought up it is thought by the Italian mathematician Luca Pacioli, in his Summa de arithmetica, geometrica, proportioni et proportionalità (Venice, 1494).
The basic premise is that a business's (or other organization's) financial condition and results of operations are best recorded in accounts. Each account maintains a "history" of changes in monetary values about a particular aspect of the business. (From Wiki)
The word "particular" is the one to watch. One might have reasonably expected it to say "all aspects of the business."
