Money, empires, and religions are all interlinked together because of how they all support the advancement of each other. Money is the base to any empire, and an empire is nothing without it. The same also goes for religion. Money makes people more cooperative and therefore more efficient due to its “win-win” nature, that satisfies all parties involved. Money also encourages empires to expand by providing them with the resources they need to grow. “Money required no technological breakthroughs, it was purely a mental revolution (Harari, 177). Money is anything that people are willing to use in order to represent the value of other things, by exchanging goods and services. Payment gives people incentive to work, and therefore civilizations can produce progress. People in turn work together because both religions and empires carry with them a sense of nationalism, which ties people together and motivates them to cooperate and grow as a collective nation rather than just as single individuals. Religions and empires also caused competition among nations and religions which created a sense of technological determinism that would cause waves of progress throughout history. Capitalism is a good example of how money can keep government going in a world where resources are scarce. Harari claims, “economic growth also requires energy and raw materials, and these are finite” (p 334). “The competition of these resources flared up into violence and genocide… in modern times, a small difference in skin color, dialect or religion has been enough to prompt one group of Sapiens to set about exterminating another group” (Harari, 17). The progress of humans is often rooted in greed and power. It’s always been a species that wants to be the best and greatest that it can be. Religion and Empire were a tool to bring people together in union in order for the elites to make more money, while the commoners strived to get richer. Studying why this is important is necessary to understand why and how humans have gotten to where they are today, and by looking at the past, we are able to see the future, so we can better interact with the present.
