Redacted.From the little I've seen of preppers sites they seem nonsense.
I'm currently digging through one right now, looking for nuggets of useful information.
As for the dollar becoming worthless; it sounds absurd. The US dollar is the worlds reserve currency. The arabs struck oil, you struck everything. You are a manufacturing, finance, academia, techological, computing, agricultural, fisheries, timber, oil, coal, gas, gold, silver etc, etc giant. A huge (330 million) skilled and educated workforce.
The U.S. dollar is the current reserve currency of the world. The reason for this is, nations buy and sell oil using U.S. dollars. Some people don't like this. Therefore, they've talked about buying and selling oil with gold instead of U.S. dollars. This action will flood the market with U.S. dollars.
