The current 90 year cycle we are in began in the period of time between 1929 great depression and the end of ww2 at which time the dollar became the dominant world currency. The 90 year cycle was the means by which the Etruscans would measure time. Every 90 years history repeats itself. 90 years is by and large the period of time from the moment that something happens (for example the founding of a city) until the point in time that all people who had lived at the first moment had died.
That's very close to the Marxist concept of the Kondratiev Cycle.
Is there something you want to tell us?
