What you're seeing over the next few videos are analyses of charts and data that are put together by "The New York Times" around trends in wealth, income, and income inequality. Our goal here is to give you extra context, extra ways to analyze the data, maybe a lens that might not be obvious when you first look at some of these graphs. Now all of us here at Khan Academy, our goal, we're a not-for-profit with a mission of providing a free world-class education for anyone, anywhere, is to provide the supports so that you can look at the data and come up with your own judgments. Our goal is not to project any opinion or any view onto you, but to give you the tools you need to form your own beliefs or your own analyses. So take a look at these videos. Hopefully, they will surface insights on some of the data, some of the visualizations that might not have been obvious otherwise, and they inform all of us on a very important debate in the world and especially in this country around how have incomes trended, how has the distribution changed over time, and where might we be going and for what reasons.
