A peculiar chapter in the 2020 presidential race ended Monday, when Bernie Sanders, after months of foot-dragging, finally released his tax returns. The odd thing was that the returns appear to be perfectly innocuous. So what was all that about?

The answer seems to be that Sanders got a lot of book royalties after the 2016 campaign, and was afraid that revealing this fact would produce headlines mocking him for now being part of the 1 Percent. Indeed, some journalists did try to make his income an issue.

This line of attack is, however, deeply stupid. Politicians who support policies that would raise their own taxes and strengthen a social safety net they’re unlikely to need aren’t being hypocrites; if anything, they’re demonstrating their civic virtue.

But failure to understand what hypocrisy means isn’t the only way our discourse about politics and inequality goes off the rails. The catchphrase “the 1 Percent” has also become a problem, obscuring the nature of class in 21st-century America.
