At the beginning of the baby boomer generation we find that the sign Sagittarius was the  ruling micro-age between c.1945 and 1960 - what better sign would rule anything that  booms other than Sagittarius? 
 Earlier between 1931 and 1945 it was the Capricorn  Micro-Age? At Sagittarius�?formative period (1945 �?1960), Capricorn was in its  powerful overflow period but both signs represent conservatism. Look at the early  1950’s with the unabashed extreme conservatism of Stalinism in the USSR and  McCarthyism in the US.
 The appearance of the Water Scorpio micro-age (c.1960�?974) introduced a swing  towards progressiveness and here we see the arrival of rock music, hippies, sexual liberation, gays, new intoxicants, reinvigorated spirituality and so on �?in other words a  strong impulse away from the straight and narrow. 
 Normally the sequence of elements in  ages and all the sub -periods is Earth, Fire, Water and Air �?two conservative signs  followed by two progressive signs and so on. Therefore the balance between  conservatives and progressives should be equal.
  In the big picture over a 26,000 years  interval this is correct. But in our neck of the 26,000 years cycle we are in full blown progressive territory due to the ages and strongly reinforced by the Water Scorpio subage overflow and Air Libra sub-age since c.1974. 
 However within this double progressive framework we are in serious mini-conservative territory. The hour hand is  progressive, the minute hand is progressive but the second hand is conservative.
