Your question (perhaps unintentionally) cuts to the heart of the matter. Any discussion income or wealth inequality in the US is inherently partisan, as one side largely insists the topic is irrelevant/is overstated/etc. and therefore is not worthy of discussion. Similarly, mentioning climate change or counting firearm deaths are also partisan topics in the US. So to answer your question -- yes, this article is partisan because it attempts to examine a topic that we have decided is inherently partisan.
