It amazes me that are people here who have a really clear understanding of the markets, though at the same time can write pieces where they sincerely believe that quite soon NYC, for example, is going to look something like the final scenes of "Zombie Flesheaters".
I think you need to consider howv resilient communities are when put under great stress e.g. London in 1940 and that even takes into account revisionist histories of the civilian experience of WW2 by people such as Alexander Calder.
I do have my stash of food and water, though no guns and ammo as this is the UK. However this is on the basis that in the time of a severe economic dislocation, I do not want to be pissed off with the hassle of having to deal with panic buyers swamping the supermarkets and petrol stations, such as happened during the fuel protests in 2000. Panic buying is more likely an outcome for us than Bristol than the city turning into something like the Warsaw Ghetto. Here in Europe, even in the unlikely outcome that should we find ourselves living under a police state, Warsaw in 1981, rather than 1941provides a guide to what more than likely would happen. In that the 1981 declaration of martial of law did see the odd "whiff of grapeshot" to show who was actually in control for the moment, but save the rationing, empty shops and a burgeoning black market, as per the experiences of my relatives who lived their at the time, life more or less went on as normal.
