I have listened a lot of Varoufakis's speeches some years back, in Greek as well as in English, when i had no idea of economics. Varoufakis was always very critical of the tendency of capitalism and market forces to create powerful companies and wealthy individuals. Lately he is all about Amazon, Google etc. In my opinion, it is a mistake to try and understand what's the purpose of money, by focusing on the consumption, rather than the production. Varoufakis falls into this trap. I have written in the past a relevant comment [1]. A recent example to illustrate what's the importance of money, is the production of CPUs, GPUs, TPUs, QubitPUs and so on. What's the more important processing unit, in the year of 2023? GPUs of course! How do we know? The price of Nvidia is going up and up. The consumers send a signal to the company which produces the most important processing unit, to increase production. So, money is an automation. It automates the answer to the question: "Which one of the processing units do we need to increase the production of?"
