Jonathan Chait: “The underlying facts, like the facts of climate change, are stark. Over the last few decades, income growth for most Americans has slowed to a crawl, while income for the very rich has exploded. That’s a reversal of the three decades following World War II, when all income groups got richer, with the poor and middle class rising at a faster rate than the rich. Crucially, the Congressional Budget Office’s new analysis shows that changes in government policy over this period have made inequality worse.”
