Kurzgesagt, the maker of the world's best explainer videos, is back with an explain about the "selfish argument for making the world a better place." The entire video is worth watching but the gist of it is this: Innovation is driven by supply and demand. Supply goes up when more people around the world are educated and become inventors, scientists, engineers, and thinkers. Demand increases as people's wealth increases and they have the means to buy new solutions to their problems. The increased supply and demand result in more innovation. So if you want nice things for yourself, you should start by helping everyone on the planet be able to have nice things, too.
