A paper for The Hamilton Project [1] analyzes the associations between education and various outcomes, highlighting a dozen economic facts on the state of education in America, with a focus on the K-12 school system, the Huffington Post reports. Not only is educational attainment highly correlated with earning potential, but over the past 40 years, incomes for college graduates have increased by more than one-third, while incomes for those earning only a high school diploma have stagnated, according to the report. Americans who fail to finish high school today earn less than comparable Americans did in 1970. The report determined that education also influences other significant outcomes, such as whether individuals marry, whether their children grow up in households with two parents and life expectancy.
