The Millionaire Next Door
Research reveals most American millionaires don't drive luxury cars or live in mansions. They're small business owners, frugal savers, and systematic investors who live below their means. The 'Big Hat, No Cattle' distinction — high income vs. actual wealth — is one of the most important financial concepts ever articulated. This book destroyed the myth that wealth looks like what you see on television.
Survivorship bias runs through the whole study: Stanley and Danko surveyed people who became millionaires, never the equally frugal strivers who went broke, so thrift gets credit that luck deserves. The wealth formula (age times income over ten) labels every young high earner a failure. And one chapter's worth of findings gets restated until it fills a book.
The case for it and the rest of the canon open with Pro.
