Earning a high income doesn’t automatically translate into high net worth. In some cases, high earners simply spend more and end up with fewer assets than more moderate earners. This situation can result from status seeking and inability to delay gratification. But sometimes, high earners with exceptional professional skills have average or below-average understanding of personal finance. In his book, The White Coat Investor (and his website of the same name), James Dahle, MD, seeks to educate physicians (who are generally high earners) on personal finance and investing so that they can enjoy the fruits of their valuable knowledge and life-saving labor.
