What about if the dollar fails?
In the event of a catastrophic financial failure, inflation goes so high that the dollar/currency becomes essentially worthless. All the savings of the citizens become worthless. Assets still exist. Real value still exists in companies, real property, goods, services, precious metals, people (labor) and so on, but the currency has no value. A new currency will be established to replace the dollar. Old dollars will be traded for the new currency at some unthinkable exchange rate. In November 1923 in Germany, Marks were traded for Rentenmarks at a rate of 1,000,000,000,000 to 1 (one trillion to one). See our History of Money and Banking. But recognize that the dollar is failing slowly; the Dow in gold today is 70% of its 1929 high.
