Fiat Currency Collapse and the 38 Trillion US Dollar Treasury Bellwether: Musk's Clear Understanding of the Crisis of Confidence in Fiat Money. He pointed out that US debt has exceeded 38.3 trillion dollars, and the continuous expansion of money supply and debt will weaken purchasing power in the long run. In 2008, Zimbabwe's inflation rate soared to 11,200,000%, and a 100 trillion dollar note had an actual purchasing power of only 25 dollars; people wanted to spend money as soon as they received it. This is not a distant history but an extreme demonstration of the collapse of fiat currency credit. In Musk's view, money is essentially an information system used to allocate labor. If someone is stranded on a deserted island, even possessing a trillion dollars is useless because there are no human resources or services to exchange. This thought experiment reveals the fragility of monetary value.
