Is the dollar really backed by nothing?

The U.S. dollar is not backed by physical commodities like gold or silver, which is often what people mean when they say it is "backed by nothing." Instead, the dollar is a Fiat currency, meaning its value is derived from the trust and confidence that people and governments have in the U.S. economy and its ability to maintain stability. This trust is reinforced by the government's authority to impose taxes and regulate the money supply. Ultimately, the dollar's value is largely based on economic factors and collective belief rather than a tangible backing.
