The folks in the discussion aren't tinfoil extremist types; we're pretty much "workin' for a livin'" who happen to talk politics. But I'm hearing more and more "disaster" scenarios.
Is it a market crash, a plague, or a natural disaster? Doesn't matter. We've learned that Grover Norquist won. The government can no longer swim.
This part of the country is not agriculturally sustainable. We talked about the native population density compared to the current population density. Not a good mix, or why our food isn't local is because local is high mountain desert.
But we are communitarian. We talked about skills (my having spent my younger years on a farm, and knowing how to carve up an animal was highly valued) and who has what tools, and I realized that we'll be OK.
