A recent Gallup Poll, conducted Jan. 20-22, finds that 31% of Americans expect to get rich at some time in their lives, and another 2% volunteer that they already are rich. The public's definition of rich means an annual income of about $120,000 or financial assets of about $1 million (each figure is the median estimate). These figures, as well as the percentage who expect to get rich, all vary considerably by gender, age, and income.
