How can all these countries owe so much money?  Why & where did they borrow it from?
By the phrasing of your question it seems that you are under the mistaken impression that countries are borrowing money from other countries, in which case it would make sense to question how everyone can be a borrower with no one on the other side of the equation. The short answer is that the debt is owed mostly to individuals and institutions that buy debt instruments. For example, you know those US savings bonds that parents are buying to save for their children's education? Well a bond is just a way to loan money to the Government in exchange for the original money plus some interest back later. It is as simple as that. I think because the debt and the deficit are usually discussed in the context of more complex macroeconomic concerns people often mistakenly assume that national debts are denominated in some shadow banking system that is hidden from the common person behind some red-tape covered bureaucracy. This is not the case here. Why did they get themselves into this much debt? The same reason the average person does, they are spending more than they bring in and are enabled by access to easy credit. Like many people they are also paying off one credit card using another one.
