Economists are the types of pseudo-intellectuals that create mathematical models, which almost never work in the real world. Anyway, as far as my understanding goes, today we live in a debts-driven-and-debts-stimulating society, where inflation has a soothing effect. Let's say the GDP is €1 trillion, inflation is 2%, debt is €0.6 trillion, which is 60% of GDP,  and economic growth is 0% then next year GDP reads €1.020  trillion and debt is still €0.6 trillion, which has magically become 'only' 58.8% of GDP. Isn't that great ?! No, it isn't, because someone needs to pay the bill, at the end of the line. Debts do exist in the real world, but they are anonymous, transformed, transferred, disguised and encapsulated within the totality of the money-system and this results in an intrinsic value of contemporary conventional currencies; each coin (real or virtual) hides this shared debt proportionally.

Now, wouldn't the world change all that if we gradually change into a debts-discouraging society driven by a deflationary currency like Bitcoin?
