As an aside I was watching a tv programme two nights ago about the 1970's in the UK, particularly 1973-4,(http://www.bbc.co.uk/programmes/b01gvr25) which were the years of the oil shock, coalition govt, coal miners strikes, 3 day week, devaluation of the pound and double digit inflation. What struck me is how similar it all seems to where we are heading now and I feel that it will be a 40 year cycle where we get to see all the same things again in 2013-4. The footage of interviews with housewives complaining about not being able to budget for their weekly shop due to the ever increasing food prices seemed particularly prescient, plus the most popular tv programme was called 'Doomwatch'! and self-sufficiency took hold. Sound familiar?!
Just my sov's worth
And to add my Groat's worth, it WAS INDEED depressing & it was that period during the 70's that led to me going overseas to Africa for many years .... and I agree that NOW is indeed getting very much like THEN.
You mentioned "Doomwatch", but don't forget the original UK "Survivors" 1970's series (which was quite good/realistic at showing how society/survivors might end up eking out a living in the event of societal collapse from ANY cause).
