"The achievement gap between children from high- and low-income families is roughly 30 to 40 percent larger among children born in 2001 than among those born twenty-five years earlier." According to a recent study, children that have a higher household income tend to do better in school as opposed to children with a lower household income. This is mainly because the higher income students get more educational opportunities, and this is beginning to form an "opportunity gap" between the two groups of students.

"The wealth of white households was 13 times the median wealth of black households in 2013, compared with eight times the wealth in 2010, according to a new Pew Research Center analysis of data from the Federal Reserve's Survey of Consumer Finances. Likewise, the wealth of white households is now more than 10 times the wealth of Hispanic households, compared with nine times the wealth in 2010." The income inequality between different races has become a significant problem in the United States. According to a recent study, the average annual income of white Americans is 13x greater than that of black Americans. This problem needs to be fixed in order to maintain a healthy democracy.
