I don't believe that looking at the past to predict the future would work in such a case.
Paris had existed for a thousand years without electricity. With each passing year, conditions improved.
The residents had evolved lifestyles and jobs that kept most clothed, housed and fed.
In a case like peak oil collapse, it will be the opposite. People are used to comfort, and the 'easy life'.
I believe that it will be a slow melt down rather than a big bang.
People will quit their jobs simply because the cannot afford to commute any longer.
A new life style will evolve in the inner cities, but it will take years to develop.
It will probably take a full generation to make this transition into a viable process.
Just like in cities of yore, there will be those that make a comfortable living, and there will be the 'have-nots'.
Once again, people will lose their land and homes.
Those with a
mortgage will be the first to fall. Just like in the Great Depression.
Those who already have 'street smarts' will be the least hurt by such an event.
There may not be jobs, as we now know them. No fixed wages or salary, nor fixed hours.
You will need to hustle to find opportunities. An odd job here, another one there.
Once again, the ability to work with your hands will ensure survival, whether in the city or on the farm.
