"Two important features seem to appear across societies that have collapsed," reads the study. "The stretching of resources due to the strain placed on the ecological carrying capacity and the economic stratification of society into Elites and Masses."
In unequal societies, researchers said, "collapse is difficult to avoid.... Elites grow and consume too much, resulting in a famine among Commoners that eventually causes the collapse of society."
Thank the gods we have so many long standing, millennia-old "Equal Societies" to compare all the real, historical empires to. Let's not forget the 3,000 year old empire of "Equa-Stonia", which has stood as a beacon of fake harmony since 1,000 years before the calendar started.
Just look at those Equastonians now, with their same amount of everything for every same person. Maybe one day, we all can have the same amount of everything. "Hey, Same-Andy, how much pollen have you got? Forty-two grains! TUT, Same-Andy, you KNOW forty-one grains is the number of grains that we all will get or else you get Same-Cancer! - the Ministrry of Devotional Ideology conducted a study which confirms it!"
Moral: make sure you always have the same number of everything, or you will die. Don't take it from me though - take it from the Equastonians. Their fake 3,000 year empire is proof that this zany theory is the truth. So help me, new-age jesus.
