that said I do think it is genuinely meant to appeal to (or rather pander to) service workers as per the campaign, just like going into local businesses and engaging with the staff, and hand-shaking with unions, etc. that politicians always do. These people are just incapable of selling it. I think this event is a strategized Republican attempt shake off some of the 'elitist' vibe that is so alienating about both parties, but that the Democrats being unashamed about is a point of Republican attack against them (and the Trump campaign picking up reactionary unions and talking about "jobs" all the time and how 'Democrats outsourced and ruined all the jobs' is part of this strategy and trajectory). It's just that Trump is a billionaire --- they are incapable of treating other humans like full people, even other rich. Just like Hillary was incapable of not acting aghast at working class living conditions. That wasn't the goal of the event, but it's who she is, in the class to which she belongs.
