Inflation means the general price level rises over time, reducing the purchasing power of money. A dollar that buys less than it used to is a practical reminder that money is not just an amount—it is a claim on real goods and services.

Moderate inflation is common in modern economies, but high inflation can distort saving, budgeting, and trust in financial systems. That is why inflation matters so much to households, central banks, and politicians alike.
