Still I think you are exaggerating. This video from Argentina shows a situation, which was rather an exception then a rule. Again, drawing a parallel to Russia’s 90s I remember there were some demonstrations and even armed fights between conflicting governments in Moscow, and I saw people getting squashed by tanks, and other much more violent footage shown on TV. So this Argentina clip is very soft, comparing to what I saw in Moscow. But overall only few people in Moscow willingly participated in these fights, very few people died. So out of 150M people only may be 1000 participated. I lived in the same city and watched all these events on TV as you watch the crime report about your neighborhood every day.
In US’s future sure there would be high unemployment, sure there would be no or less excesses, sure it would be very hard time for some people, sure there would be high crime rate, but I don't see people shooting at each other becoming a norm or even a problem. All this is given that on average Americans are as civilized as people in Europe for example.
If you consider average American to be psychotic and bipolar nut then all gloves are offAnd you are right.
I get your point and agree to a large degree....a certain percentage are going to capitalize on an opportunity to loot and riot (a given)...the rest will probably take it well if they still have groceries....if the currency fails and they have to spend it as fast as they get it, it may be very interesting.
I believe the Argentina clip shows the people pissed because their banks were locked and whatever "wealth" they had, they couldn't get to (maybe like Enron employees watching their stocks become worthless).
I would expect widespread violence if the Gov. tries to force people to do things or tries to confiscate things from the public.
