When the system crashes no-one will take control.
That is what a crash is.
There will be a reset—and that comes after no-one knows.
Look at what happened after the Roman Empire collapsed. There were a thousand years of chaos and nearly fifteen hundred before Karl Marx brewed his toxic mix.
“that comes after no one knows”
I have an idea. We haven’t had any collapse so complete as you describe, but every trough of the business cycle since the New Deal, some of which were close to a total collapse, has resulted in more government, except perhaps 81. But that wasn’t fundamentally smaller government, just temporarily different government. Why should I expect anything different?
What are the nearest approaches to total collapse in the relatively recent past? Germany and Russia in the 20s, both of whom experienced war deprivation and hyperinflation. Both emerged with Bigger Government, Russia after the stutter step of the New Economic Policy, and Germany in 32 by handing over their republic to the Nazis.
It is true the downfall of Rome resulted in less government. But civilization went with it. It’s an open question whether civilization is preferable to other ways of living. I still value it.
