Today marks "Equal Pay Day," the day when women's pay finally catches up to men's pay from last year. You'll have to forgive me for not cheering too loudly. Each year Equal Pay Day highlights how far we still have to go in the fight for pay equity, and it's striking how little headway has been made on closing the gap in recent years, with progress all but stagnating in the past decade. Across the board, women continue to be paid less than their male counterparts -- a fact that takes on new significance in an election year where the views of the Republican presidential candidates on the gender pay gap range from dismissive to downright hostile. But the numbers speak for themselves: according to the latest data, women earn on average 79 cents for every dollar that men earn. When you consider a full lifetime of work, the scope of inequality becomes far more dramatic. A new report from the National Women's Law Center on the "lifetime wage gap" shows that across 40 years of working, based on the current figures, women lose more than $430,000. When you break down the numbers by race, it's even more stark; African-American women lose over $877,000, and Latinas more than a million dollars. When women are making hundreds of thousands of dollars less than men over a lifetime, it affects not only women's financial stability while working and during retirement, but also the financial stability of our families. Not to mention that it's spectacularly unfair. A gender pay gap exists for women in almost all occupations, from teachers to lawyers to cooks to mail carriers, and even in the entertainment field. Demos reports that for retail salespeople, the most common occupation in the country, the gender pay disparity is "particularly stark," with women who are working full-time earning just 68 cents for each dollar earned by their male co-workers. For women struggling financially, the earnings lost simply for being a woman can mean the difference between barely making ends meet and being forced to choose between basic necessities like food and rent. When you look at the presidential candidates' stances on pay equity, it's clear that the 2016 election will be a pivotal moment for whether progress is possible in the near future. Trump claims to "love equal pay," but says he won't support the legislative efforts necessary to make it happen. At an event last year, he told a woman asking about the pay gap that "you're gonna make the same if you do as good a job." Sen. Ted Cruz voted against the Paycheck Fairness Act and derided it as a "political show vote." A 2014 newspaper investigation found that in Gov. John Kasich's office, women were paid nearly $10 less per hour than men, yet on the campaign trail, Kasich blamed not discrimination, but paid leave laws, for causing the wage gap! Despite Republicans' dismissal of the issue, equal pay for equal work remains a goal rather than a reality for women across the country. And until we close the gap, Equal Pay Day will remain an unhappy reminder of this continuing inequality.
