Basically permaculture is about improving your soil and designing and building systems that work, while constantly aiming to close the loop.
Obviously not owning land is a major part of the problem as all your effort can be wiped away on a whim of the land lord.
So for you to build systems is of very little benefit to you,long term.
Your situation is not perfect for a collapse scenario
Basic organics that includes money and shops in the loop isnt going to hold up in a collapse scenario.
You need to own land debt free or as in Cuba use land debt free which isnt going to happen in the US.
....and set up sustainable systems with a view to the long term.
* This is only if you believe that there will be a collapse scenario where you get forced from your land job and food supply and shelter.
If not your system may see you through.
This article may help.

Basically if you have land and set up a self sustaining system the amount of money you need to survive will massively decrease.
As you need less money to survive, your leisure time increases and so should your standard of living.
If part of that system is to educate people on how to do the same thats cool, if its making jam thats cool, if its raising biodynamic beef and chickens and eggs thats cool,If its ecotourism thats cool.
If you make nothing and your wife can make money in the medical profession thats cool too, but its not going to be sustainable unless you use it to invest in systems and infrastructure that will make it sustainable for when its gone.
In a worst case scenario, if money is worthless, the only thing you can trade is skills and food and shiny things.
Shiny things will only have value if they too can be traded for food and skills.
If you can sort your water,food,energy and shelter for virtually nothing your doing pretty well, whether it totally collapses or not.
Obviously it takes a paradigm shift.
