''The Millionaire Next Door: The Surprising Secrets of America's Wealthy'' (ISBN 0-671-01520-6) is a 1996 book by Thomas J. Stanley and William D. Danko. This book is a compilation of research done by the two authors in the profiles of 'millionaires'. In this case they used the term 'millionaire' to denote U.S. households with net-worths exceeding one million dollars (USD). The authors compare the behaviour of those they call ''UAWs (Under Accumulators of Wealth)'' and those who are ''PAWs (Prodigious Accumulator of Wealth)''. ==UAWs versus PAWs== Under Accumulator of Wealth (UAW) is a name coined by the authors used to represent individuals who have a low net wealth compared to their income. A $250,000 per year doctor is an "Under Accumulator of Wealth" if his/her net worth is less than the product of their age and one tenth of his/her realized pretax income.〔Stanley, Thomas, and William Danko. ''The Millionaire Next Door''. New York: Pocket Books, 1996.〕 Take for example a 50-year-old doctor earning $250,000, according to the formula she should have (50 *250,000 *10%) or about $1.25 million in net worth. If her net worth is lower, she is an "Under Accumulator". The UAW style is based more on consumption of income rather than on the method of saving income. Prodigious Accumulators of Wealth (PAW) is the reciprocal of the more common UAW, accumulating usually well over the product of the individual’s age and one tenth of his/her realized pretax income and are usually considered to be millionaires; however, not all are. The authors define an Average Accumulator of Wealth (AAW) as having a net worth equal to one-tenth their age multiplied by their current annual income from all sources. E.g., a 50-year-old person who over the past twelve months earned employment income of $45,000 and investment income of $5,000 should have an expected net worth of $250,000. An "Under Accumulator of Wealth (UAW)" would have half that amount, and a "Prodigious Accumulator of Wealth (PAW)" would have two times. This metric has been criticized since, for example, a 20-year-old making $50k a year should have a net worth of $100k to be considered an "average accumulator of wealth". That makes little sense since it would take a new graduate years of strong savings and investments to accumulate that amount. The formula fails to take into account compounding interest; younger people up to age 45 or so will generally have much less as a percentage of income than older wealth accumulators due to compounded growth. Most of the millionaire households that they profiled did not have the extravagant lifestyles that most people would assume. This finding is backed up by surveys indicating how little these millionaire households have spent on such things as cars, watches, suits, and other luxury products/services. Most importantly, the book gives a list of reasons for why these people managed to accumulate so much wealth (the top one being that "They live ''below'' their means"). The authors make a distinction between the 'Balance Sheet Affluent' (those with actual wealth, or high-net-worth) and the 'Income Affluent' (those with a high income, but little actual wealth, or low net-worth). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「The Millionaire Next Door」の詳細全文を読む スポンサード リンク
