I’ve noticed how humans get too caught up in the minutiae to see the big picture, the grand scale of things. Look at what all we’ve done to Mother Earth in the last couple hundred hears in comparison to how long she’s been around.
I like that 80 year theory…not only does it match up to a human lifespan it matches up with a lot of key events in American History:
1789-1809 Spring
1809-1829 Summer
1829-1861 Fall – Ends with Civil War
1849-1869 Winter
1869-1889 Spring
1889-1909 Summer – Industrialization
1909-1929 Fall – WWI, ends with Stock Market Crash
1929-1949 Winter – Great Depression, WWII
1949-1964 Spring
1964-1984 Summer
1984-2008 Fall – Ends with Wall Street collapse
2008-2028 Winter
I’ll have to think about it more, but the author may be on to something…
