Speaking anecdotally, I’m pretty sure you’re right on that one. In my circle of (millenial / lefty) friends it’s basically seen as common sense. Among the average person I interact with, however, such as at work, it’s seen as a fringe idea. And I’m not even advocating for eating them in the revolutionary sense - just taxing the rich in a way that doesn’t allow any one person/family to horde egregious amounts of wealth to the point that they can unduly influence society with their power.
