Thomas J. Stanley and William D. Danko · 88 weeksNorth and South answer the same budget question
SHORT SOURCE EXCERPT“Dr. North is very similar to Dr. South in age, income, and family composition.”
After introducing two physicians with similar backgrounds and different wealth profiles, the chapter asks whether each household uses an annual budget. South answers negatively and North affirmatively; subsequent sections keep returning to their household choices.
The repeated names and repeated question make the contrast easy to track. The scene supplies a compact model of the chapter’s larger arrangement: comparable starting conditions, different decisions, and different reported positions.
The source in context.
Dr. North and Dr. South have similar ages, incomes, and family composition but different accumulation and consumption patterns. The chapter returns to them across budgeting, family habits, cars, worries, and planning, then closes with a case about selecting advisers.

Its limit
The cases use pseudonyms and selected traits. Their similarity is an authorial comparison, not an experiment controlling all causes.
