洛克菲勒家族在美国是首富,但是他们家族中没有一个人挥金如土。戴维的祖父老洛克菲勒在他年轻时候就开始记录个人的收支账目,每一分钱都要在这个账目上写出用途和使用时间,每一笔开支必须有正当而可靠的理由。老约翰在临死时将他的传统交给了儿子小约翰·洛克菲勒。小洛克菲勒继承了父亲的光荣传统, 又把它像接力棒一样传了下去。 The Rockefeller family is the richest man in the United States, but none of their families are making big spenders. David’s grandfather, Old Rockefeller, began recording personal income and expenditure accounts when he was young, writing down the purpose and duration of each penny on this account, and for every expense there must be valid and justifiable reasons. Old John handed his life to his son, John Rockefeller, on his deathbed. Little Rockefeller inherited his father’s glorious tradition, and passed it on like a baton.
