This policy brief discusses an empirical simulation exercise that gauges the plausible impact of increased rates of college attainment on a variety of measures of income inequality and economic insecurity. The results reveal that increasing college attainment would shrink gaps between the 90th percentile and lower half of the earnings distribution, as well as between the median and bottom, in most cases. Increased college degree attainment would meaningfully raise economic security for individuals near the bottom of the earnings distribution and reduce poverty rates. However, increases in college attainment would not reduce gaps at the very top of the distribution--for instance, the 99/90 percentile ratio. The policy prescription of increased educational attainment should thus appeal to those whose primary concern is the economic security of lower-income individuals, but it will not satisfy the goals of reduced income shares at the top of the distribution.
