I'm interpreting your discussion prompt as a request for an economic crises 101 survival guide. Your question is quite vague though, and it could be interpreted in many other ways as well.

I think one could come up with some general strategies for being less vulnerable to rough economic climates. Moving to the country-side and setting up a self-sufficient farmstead is a naive example.

Supposing you want to actually live in a community, I guess one of the priorities is being able to maintain at least some economic activity in crises. So the question is, what kind of economic activity is resilient (has been resilient) to economic crises?

Can you elaborate? What financial crisis are we talking about here?

From recently dramatic stock market changes, it seems financial crisis is closing. and I hope I am wrong.
