Two findings stand out in a new study from the Economic Policy Institute (pdf) on black-white wage gaps in the United States:
First, since 1979, the gap between all workers’ wages—black and white, women and men—and productivity has increased dramatically. Thus, while productivity increased by over 60 percent, wages for white workers rose by only 22.2 percent and black wages by even less, 13.1 percent.
Second, wages for African American have grown more slowly (or, in the case of men, fallen by a greater amount) than those of their white counterparts. As a result, pay disparities by race and ethnicity have expanded since 1979. For example, white women’s wages increased by 30.2 percent and black women’s wages by only 12.8 percent. And while men’s wages actually declined, they fell by 3.1 percent for white men and even more, by 7.2 percent, for black men. Thus, the overall black-white wage gap increased from 18.1 percent in 1979 to 26.7 percent in 2015.
It is pretty clear from the report that overall wage stagnation (especially for the majority of workers, i.e., those below the 90th percentile), in conjunction with lax enforcement of anti-discrimination laws, led to higher wage disparities by race and ethnicity.
But, and this goes beyond the report, we also need to consider the other side of that relationship—that increased racial and ethnic disparities reinforce the growing gap between productivity and the wages of all workers. Black workers are paid less than their white counterparts (of both genders), and all workers’ wages are as a result less than they otherwise would be.
In the end, then, wealthy individuals and large corporations, who capture the resulting surplus, are the only ones who benefit from racial and ethnic wage disparities.
