While the Washington Post's demonstrable history of political bias is hardly news, the outlet may have reached new levels of hypocrisy when it comes to the topic of "income inequality," which it has bemoaned a documented 558 times this year alone.

Oddly, The Post, while championing the plight of “Harvard Business School alumni" and their concern with "rising inequality, worsening poverty and the stagnating middle class," failed to mention that its owner, Democratic donor and Amazon CEO Jeffrey Bezos, just added $16.5 Billion to his own personal wealth this same year.

Bezos made 899,521 times the median household income in the United States -- $52,250. Were Bezos a nation, the $16.5 billion would give him a GDP rank of 150, just below Kosovo and above 81 nations including Guinea and Iceland.

According to a report filed by NewsBusters, The Post mentioned the scourge of "income inequality" 156 times in print and another 404 in times in blogs, only once invoking Bezos’ name. Below is a sampling of the outlet’s crusade:

• “This fresh evidence of stubborn income inequality comes as the issue of Americans' financial well-being factors prominently in the 2016 presidential campaign.” – Sept. 17, 2015.
• “Income inequality bedevils the United States, as does debt, of the public and private varieties.” – An Aug. 27, 2015, editorial. (Does Bezos read his own paper?)
• “Income inequality and ensuring that hard work is adequately rewarded are likely to resonate with voters next year.” Another editorial, this one from Aug. 6, 2015.
• Many of the stories cited comments from socialist presidential candidate Sen. Bernie Sanders (running as a Democrat). “During his swing, Sanders, the independent senator from Vermont, drew more than 2,500 people to a convention center here -- a record crowd for Iowa. Supporters leapt to their feet and screamed as he decried the ‘grotesque level’ of income inequality in the country and the outsize influence of the ‘billionaire class’ on its politics.” (Wonder if Sanders considers newspaper owners as having influence on politics.

Only one Post column, penned by George Will, mentioned billionaire Bezos, though in a complimentary way. Will's article, titled “Income inequality is good,” fawned over those who embody the most glaring examples of the rich-poor-gap today, claiming the U.S. "needs more billionaires" like Bezos and Facebook CEO Mark Zuckerberg.

As up-and-coming generations are buried by student loan debt and find themselves perpetually out of work despite their best efforts, as the American middle class fades into obscurity, the notion of “income inequality” is a meaningful issue worthy of careful consideration, not meant as fodder for billionaires’ PR campaigns.
