I tell my students that there is…and it is a working presumption in my classroom when we talk about structural sin and catholic social teaching.  But Carrie Lukas of the Wall Street Journal has written an article that has complicated the issue for me.  Consider:

The unemployment rate is consistently higher among men than among women. The Bureau of Labor Statistics reports that 9.3% of men over the age of 16 are currently out of work. The figure for women is 8.3%. Unemployment fell for both sexes over the past year, but labor force participation (the percentage of working age people employed) also dropped. The participation rate fell more among men (to 70.4% today from 71.4% in March 2010) than women (to 58.3% from 58.8%). That means much of the improvement in unemployment numbers comes from discouraged workers—particularly male ones—giving up their job searches entirely.

Men have been hit harder by this recession because they tend to work in fields like construction, manufacturing and trucking, which are disproportionately affected by bad economic conditions. Women cluster in more insulated occupations, such as teaching, health care and service industries.

But, as Lukas notes, women only make about 77% of what men do…and this is what I try to get my students to understand.  But she has an interesting take on this statistic:

The Department of Labor’s Time Use survey shows that full-time working women spend an average of 8.01 hours per day on the job, compared to 8.75 hours for full-time working men. One would expect that someone who works 9% more would also earn more. This one fact alone accounts for more than a third of the wage gap.

Choice of occupation also plays an important role in earnings. While feminists suggest that women are coerced into lower-paying job sectors, most women know that something else is often at work. Women gravitate toward jobs with fewer risks, more comfortable conditions, regular hours, more personal fulfillment and greater flexibility. Simply put, many women—not all, but enough to have a big impact on the statistics—are willing to trade higher pay for other desirable job characteristics.

Men, by contrast, often take on jobs that involve physical labor, outdoor work, overnight shifts and dangerous conditions (which is also why men suffer the overwhelming majority of injuries and deaths at the workplace). They put up with these unpleasant factors so that they can earn more.

She claims that things get even less problematic when one considers more specific social situations of workers:

Recent studies have shown that the wage gap shrinks—or even reverses—when relevant factors are taken into account and comparisons are made between men and women in similar circumstances. In a 2010 study of single, childless urban workers between the ages of 22 and 30, the research firm Reach Advisors found that women earned an average of 8% more than their male counterparts. Given that women are outpacing men in educational attainment, and that our economy is increasingly geared toward knowledge-based jobs, it makes sense that women’s earnings are going up compared to men’s.

Though this certainly complicates the issue for me, it still seems that women being primarily responsible for child-rearing puts them at a competitive disadvantage in the workforce…and that this is de facto structural sexism.  But I’d be interested in comments from people who know more about this stuff than I do.  What is the reply here?
