We're in a recession now, as today's headline in the NY Times proves: "Bernanke Nods at Possibility of a Recession." I.e., we're in a recession.
If there is another Depression, it's going to hit the average person much harder. Back in 1929 many more Americans lived in rural areas, and more importantly, farmed their land. They were used to much fewer material goods than today's American, and they were far more self-sufficient. They were used to growing their own food, and they new how to cook from scratch. Many more knew how to sew, and thus could fix clothes which were old or ripped. Their homes were simpler, and they could do many of their own repairs. Hell, they even were better at first aid and tending to common illnesses.
Compare that to the average American today who relies on McDonalds for food, Wal-Mart for new clothing when the old wears out, and is lucky if he or she can change a lightbulb, much less change an outlet.
If the machine breaks down, a lot of people will find themselves needing to fend for their basic needs in ways for which they are completely unprepared.
Stock up on dried grains and dried beans, and toilet paper. Don't forget the toilet paper.
