It's not a perfect fit, because you have WWI and the Great Depression in there...

The Great Depression started the Crises Season, which gave birth to the Silent Generation, and that ended with WWII, which marked the beginning of the Season of the High, which gave birth to the Baby Boomers. What you pointed out there, were the endings of the "80 years cycle" or Saeculum, but those ending points are generally preceded 20 years prior, by an economic collapse. We are moving towards war, as the cycle goes from Great Depression 1929 to Great Recession 2009.
