Great Mutations and Civilizational Burnout

https://empoweringastrology.com/the-great-mutation-from-earth-to-air/ 

There is an important astrological cycle that occurs every twenty years, conjunctions of Jupiter and Saturn. These signify societal expansion vs. contraction. There are twelve zodiac signs and four elements. Three signs each fall in each element of fire, earth, water and air. The great conjunctions occur in an 800 year cycle where for about 200 years Jupiter and Saturn meet in one element. The great mutation is when they switch to another element. The cycle moves from water to fire to earth to air. The severest collapse, dark ages appear to occur in air signs. I would call this civilizational burnout. In year 400-600, 1200-1400 and now from 200-2200 we could expect similar. The post Roman Dark Ages, plague, mongol invasions, transition to renaissance, early modern and now people are not wanting to work, marry, losing interest in everything. This downturn is moral not economic or structural. When a person reaches sixty they yearn for retirement. At eighty death is desired. I think civilizations work the same.
