Bernie Sanders loves to antagonize billionaires, even if it hurts their feelings. Usually, Sanders rails against the way they have used our political system to enrich themselves at the expense of the working class. Over and over again, Sanders points out that politicians like Pete Buttigieg oppose pro-worker policies like Medicare for All, because their campaigns are funded by billionaires and insurance company executives.

But at the February debate in Nevada, Sanders suggested a deeper reason that “billionaires should not exist.” After Michael Bloomberg asserted that he “worked very hard” to earn his more than $60 billion fortune, Sanders responded: “You know what, Mr Bloomberg, it wasn’t you who made all that money. Maybe your workers had some role in that as well, and it is important that those workers share the benefits.”

We don’t hear this kind of rhetoric very often in American politics, on prime-time TV. But Bernie is right: Bloomberg’s gains are ill-gotten. In fact, all the wealth that the ultrarich hoard and leverage in their own interests has been stolen from the working class and from the planet we share.
