While Great societies are well great, nothing can last forever. Many great societies that people thought will never die have fallen to various things. Take rome, they fell because inflation of money, which didn't allow for much spending. Or the Nazi’s. That Nazi government was very corrupt and fell because of what they did. Or even the Etruscans. They were overthrown by the very people they governed. So Societies fall for many reasons, including corrupt leaders, money inflation, and social revolution.
Societies fall politically because of things like corrupt government, or invasion.One example is in Saga where the dark queen of the world doesn't care for anyone but herself, and controls the lives of everyone. The Citizens of the world lived in poverty, because the government neglected them. As said in the book, “This world with the humans, pathetic creatures that are so easy to manipulate.”(223 Kostick)
Another good example just like Saga is Nazi Germany, where Adolf Hitler ruled with an iron fist. He strictly controlled all forms of media, and killed anyone who disagreed with him. Hitler did not care about his citizens, he only cared about his own personal agenda. As said on Wikipedia, “The Holocaust and Germany's war in the East was based on Hitler's long-standing view that the Jews were the great enemy of the German people and that Lebensraum was needed for the expansion of Germany. He focused on Eastern Europe for this expansion, aiming to defeat Poland and the Soviet Union and on removing or killing the Jews and Slavs.” Corrupt leaders tend to get nowhere, because the citizens don't tend to tolerate them. Next up we have Economic reasons.
A Economic reason that societies fall is inflation of money, and debt. In the world of Saga, everything is overpriced due to the constant printing of money. To make things worse, the wages for workers don't go up in correlation to the price of money, rendering everything almost impossible to obtain. The printed money is coming from, shocker, the Queen in a attempt to make life even worse. As stated, “Of course We print money. Do you really think I want the citizens to have anything?” (310 Kostick)
In Rome, the value of money was next to nothing because of excessive military spending. The result of this is the...
