What’s keeping wages down and driving inequality up in Washington

The State of Working Washington 2018: Part 3

Several factors are contributing to stagnating wages and growing inequality, including declining unionization, and gaps in pay by gender and race rooted in historic barriers and systemic discrimination.

Declining Unionization

While no single factor is entirely responsible for the growth in inequality, declining unionization has been a contributing influence.[8] Following the passage of the National Labor Relations Act in 1935, the spread of collective bargaining led to decades of faster and fairer economic growth that persisted until the late 1970s.


Since the 1970s, however, declining unionization has fueled rising inequality and stalled economic progress for the middle class. Nationally from 1972 to 2007, one-third of the rise in wage inequality among men, and one-fifth of the rise in wage inequality among women, is attributable to declining unionization. Among men, the erosion of collective bargaining has been the largest single factor driving a wedge between middle- and high-wage workers.[9]


Gender Pay Discrimination

Another persistent source of income inequality is the gender pay gap. In Washington, a typical woman (or one earning median wage) is paid 22 cents less per dollar paid to a typical man.[10] While the gender pay gap has declined since 1979, the state has not made any significant or lasting progress in closing the gap since the late 1990’s.


The gender pay gap is not an education gap – nor is it solely a product of having fewer women in some industries than others. At every level of education, women are paid less than similarly educated men – and the wage gap rises with additional education. The gap also exists in all industries – including those in which more women are employed than men.[11]

Racial Pay Discrimination

The National Picture

All demographic groups are experiencing growing income inequality and slowing growth in living standards. At the national level, since 1979 median hourly real wage growth has fallen short of productivity growth for all groups of workers, regardless of race or gender. However, these wage trends are markedly different for men than for women, and for blacks relative to whites.

Median hourly wages for both white and black men have fallen, with black men suffering larger losses (7.2 percent, compared a 3.0 percent loss for white men). While median hourly wages of black and white women have increased, white women’s wages grew much more (30.2 percent) than those of black women (12.8 percent).[12]


The Pacific Region

In the Pacific region of the U.S. (Washington, Oregon, California, Alaska, Hawaii), pay disparities by race and ethnicity have remained unchanged or have expanded relative to 1979 levels. The median wage for White workers increased to $23.95/hour (+$4.69), while for Hispanic workers it increased to just $14.99/hour (+$3.78), and for Black workers it declined slightly to $16.92/hour (-$0.10).[13]


Put another way: in 2017 a typical (or median) Black worker was paid 29 cents less, and a Hispanic/Latinx worker 37 cents less, per dollar paid to a typical White worker. For Black workers, that gap has more than doubled since 1979, and for Hispanic/Latinx workers the gap has not narrowed substantially since the late 1980s.


Washington State

In Washington, the gap in average monthly wages between White workers and workers who are people of color grew dramatically between 1990 and 2017 (save for workers of Asian descent, a subset of whom are employed in very high-wage information, technology and professional sectors). In 2017 alone, the racial gap cost workers of color an average $12,228 to $20,838/year.[14]

As with the gender pay gap, workers of color cannot educate themselves out of pay disparities. Nationally, as of January 2017, average hourly wages for White college graduates are far higher ($31.83) than for Black college graduates ($25.77) – and the national unemployment rate for Black college graduates was 4.0 percent, compared to 2.6 percent for White college graduates.[15],[16]
