Amount of money in the world is not fixed

“For most of human history, the world was a dark place. The cost of lighting was so profoundly high that when the sun went down people often just huddled in their shack or hut and waited for dawn. The story of how we got from huddling in the dark to having as much light as we want at the flick of a switch explains a ridiculous amount about the world. It explains why most people on Earth no longer have to worry constantly about starving to death. It explains why most people aren’t subsistence farmers—why we can have a world of people who make their living as personal trainers and HR professionals and plumbers. It explains climate change. It also explains why the amount of money in the world is not fixed, why one person’s gain is not another’s loss”
