Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it.
The real power here lies in its moral dimension—Einstein isn't simply saying that compound interest works mathematically (which is obvious), but that understanding it separates the prosperous from the perpetually broke, making financial literacy a question of justice. Most people treat debt and savings as separate problems, when really they're the same mechanism working in opposite directions: a credit card at 20% annual interest compounds against you with the same relentless force that a retirement account at 7% compounds for you. A young person who borrows $5,000 for a car at high interest will spend decades paying far more than the original sum, while their peer who invests even modest savings watches that amount quietly multiply—same mathematics, opposite destinies. Einstein's droll attribution to the "eighth wonder" transforms what could be dry financial advice into something closer to a warning about the inequality built into our economic system.
