No one is forcing blacks to devalue education (except themselves).

Black and Hispanic youth are more likely than whites or Asians to have dropped out of high school. In 2013, five percent of whites ages 16 to 24 were not enrolled in school and had not completed high school, compared with eight percent of blacks, and 12 percent of Hispanics. (Figure 1) The high rate for Hispanics is partly the result of the high proportion of immigrants in this age group who never attended school in the U.S.[24] Asian youth had the lowest rate of all the racial and ethnic groups tabulated here, at three percent.

The average dropout can expect to earn an annual income of $20,241, according to the U.S. Census Bureau (PDF). That’s a full $10,386 less than the typical high school graduate, and $36,424 less than someone with a bachelor’s degree.
