Jumia Books The Millionaire Next Door By Thomas J. Stanley, White

The authors compare the behaviour of those they call "UAWs" (Under Accumulators of Wealth) and those who are "PAWs" (Prodigious Accumulators of Wealth). Their findings, that millionaires are disproportionately clustered in middle-class and blue-collar neighborhoods and not in more affluent or white-collar communities, came as a surprise to the authors who anticipated the contrary. Stanley and Danko's book explains why, noting that high-income white-collar professionals are more likely to devote their income to luxury goods or status items, thus neglecting savings and investments.
