The saeculum is a product of generations and their interplay, overlap and interaction.
It’s slowing because lifespans are getting longer, which means the relationship between generations elongates.
If this were the 1850s most boomers would all be dead and millennials would have their wealth. That’s not the case tho because even the generation preceding boomers is still very much alive and even still holding onto positions of public power.
Biden is a late stage silent gen member.
I think next we elect a true boomer- be it trunp or RFK jr
And we ride into all out global war being led by a boomer, and fought by millennials. Whoever becomes Prez next will be perceived very differently after the crisis that they lead us through, if it is successfully navigated.
