How Inflation Silently Erodes Wealth
Inflation is the steady rise in the prices of goods and services. When cash sits idle in a zero-interest checking account, it loses purchasing power year after year. To protect long-term wealth, capital must be invested in assets (stocks, real estate, Treasury inflation-protected securities) that outpace the rate of inflation.
