Despite the average American holding only about $60 in cash, the per capita amount of U.S. currency is over $7,000. This is because the vast majority—as much as five-eighths—of physical U.S. currency, particularly $100 bills, is held offshore as a global store of value.

By establishing the dollar as the world's reserve currency after WWII, the U.S. gained the unique power to run huge debts and print money. This effectively forced other countries holding and trading dollars to absorb the inflationary costs of U.S. spending, funding the 'American dream' at global expense.

The U.S. economy's ability to consume more than it produces is not due to superior productivity but to the dollar's role as the world's reserve currency. This allows the U.S. to export paper currency and import real goods, a privilege that is now at risk as the world diversifies away from the dollar.

The term "fiat money" is a misleading veil. A currency's true value comes from the quality of assets on commercial bank balance sheets and the robust regulatory framework (like the FDIC) that prevents systemic failures, not from a simple government declaration.

Core components of today's financial landscape, including FDIC insurance, Social Security, and even the 30-year mortgage, were not products of gradual evolution. They were specific policies created rapidly out of the financial ashes of the Great Depression, demonstrating how systemic shocks can accelerate fundamental structural reforms.

The U.S. maintains global financial dominance less through military might and more through the Federal Reserve's currency swap lines. These agreements backstop the vast pool of dollars created by foreign banks, making the Fed the indispensable lender of last resort for the entire global system.

The primary, world-changing use case for stablecoins isn't cheaper domestic payments. It's providing global, frictionless access to the U.S. dollar. This allows citizens in countries with unstable currencies or untrustworthy central banks to opt-in to the U.S. financial system, effectively exporting America's most powerful product.

The dollar became the world's currency not only because of U.S. economic strength but because American authorities allowed foreign banks to create dollars abroad (Eurodollars). This decentralized creation happened first; only later did the Fed step in to backstop a global system it did not initially control.

We take for granted that a dollar at Chase is worth the same as one at Bank of America. This "no-questions-asked" property is the result of a century of regulation, contrasting sharply with the 19th-century "free banking era" where different banks' notes had fluctuating exchange rates.
