It’s worth noting that what someone puts on a sign doesn’t necessarily indicate what they really care most about, especially if what’s on the sign is more socially acceptable than what they really care about. So I don’t think the findings here are inconsistent with what annacaffeina says. (They are probably, albeit not very strong, evidence against what she says, though. Only “probably” because it could be that the other sign-slogans—especially the more generically-political ones—are evidence about the sort of person waving the sign; maybe some of those slogans are more characteristic of wealthier people who want the service industry serving them again than of poorer service-industry employees who want to be at work again.)
