How New Money and Old Money Differ (Maybe)

Writing in the Journal of Financial Planning, James Grubman and Dennis T. Jaffe sort High Net Worth families into two groups: immigrants (new money) and natives (old money):

Clients who come to wealth during their lifetime have fundamental differences in life experience, identity, and adjustment compared with clients who come from family wealth. Much like the differences between immigrants and native-born citizens, acquirers and inheritors experience the Land of Wealth from unique perspectives. They also face different dilemmas in parenting effectively and in making choices about estate planning.

Interesting slant, though you may question whether New Money comes only in plain vanilla. What about Greenwich hedge fund managers and other tutti fruitis?
