How To Survive Total Economic Collapse

**FIRST OF ALL, THIS NOT A ACTUALLY A HOW - TO, IT IS MORE OF A COMMENTARY** When Man first emerged - whichever way you believe it happened - we had to not only figure out our own food sources, we had to learn how to make fire, make our own clothes, build our own shelters, etc. As technology has progressed, many people have lost and forgotten the 'old ways'. What concerns me is - if the economy were to completely collapse - how many people truly know how to survive? How many people know how to hunt food, forage for fruits and berries - and know how to tell the good ones from the poisonous ones - or build a shelter? How many people would actually survive if there were no cell phones, electricity, etc.? A friend of mine had a friend that was living in Louisiana when the last hurricane hit; the friend was eating cold food out of cans because she DIDN'T KNOW HOW TO BUILD A FIRE. This really concerns me; too many people are so dependent on technology, electricity, and such, that they would probably starve to death because they don't have the basic skills they need to survive! There is no easy solution to the problem, and it may not ever be an issue, but what if?
