Final answer:
Since the 1980s, the income of older people in the United States has grown faster than the income of younger people.
Step-by-step explanation:
Since the 1980s, the income of older people in the United States has grown faster than the income of younger people. According to the U.S. Census Bureau, in 1990 senior citizens reported earning 36 percent more income on average than they did in 1980, which was five times the rate of increase for people under the age of thirty-five. This trend of growing income for older people can be attributed to factors such as better retirement programs offered by private employers and governments.
