When I was eleven, I had a theory that there was exactly so much money in the world that you could pay for every single thing that exists on Earth. But there was a problem: while both the money and the things themselves were considered valuable, only the things had actual value - the value of money was only symbolic. So our economic system assumed that there was twice as much wealth in the world than there actually was. This made the system inherently unstable and created a need to devalue money and property. That was my explanation for inflation.
