Yes, the economy is kind of tanking at the moment. Yes, the government has behaved rather worryingly in recent years (although it is hard to name many years, in the past hundred or so, when it *hasn't* acted rather worryingly in *some* respects).
But please don't get all swept away in a largely media and internet-spawned "fad".
Think back to even just the past 10 years. At various times, people have been discussing/predicting/preparing for, with EXACTLY THE SAME SINCERITY AND FEAR:
-collapse of civilization as we know it due to Y2K computer problems
-everyone should stock up on super-fine particle dust masks and anthrax antibiotics with them
-terrorists about to do lots of horrible things in every small town everywhere
-SARS, the new global pandemic
etc etc etc etc
And that's just the past decade. Those who are past their 20's will have gone through a whole bunch other panics, each equally plausible and important sounding, each equally disappearing (altogether, or into the general background noise of life) after a coupla months or years.
Just because people are feeling inclined (one might cynically say 'being encouraged') to run about with their hands in the air about we're all going to run out of food, does not necessarily make it any more LIKELY to happen.
If you ask me, this culture has become so fat and lazy that we feel entitled to have nothing bad ever happen to us and thus like to overreact like the world is ending to anything that smacks of a threat or an adjustment of circumstances. Plus it in the media's best interests to take this and run with it as far and wide as people will let 'em.
Realistically, just because things get bad doesn't mean they get horrible. And even food availability during the worst of the Depression, or rationing in WWII Britain, would be considered pretty luxurious circumstances in a lot of parts of the world.
People survive. How? Not by worrying, not by creating doomsday scenarios, not by saying Oh I Could Never... they survive by simply surviving, by putting one foot ahead of the other, by DOING. And the most successful survive by making a lifelong habit of it, not something special you try to put on for dire circumstances.
JMHO,
Pat
