About the role of credit in the economy

How the Economic Machine Works by Ray Dalio

The economy works like a simple machine.
But many people don’t understand it— or they don’t agree on how it works — and this has led to a lot of needless economic suffering. I feel a deep sense of responsibility to share my simple but practical economic template. Though it’s unconventional, it has helped me to anticipate and sidestep the global financial crisis, and has worked well for me for over 30 years.

An economy is simply the sum of the transactions that make it up. A transaction is a simple thing. Because there are a lot of them, the economy looks more complex than it really is. If instead of looking at it from the top down, we look at it from the transaction up, it is much easier to understand.
