The only act here is to convince others that the crazy shouting is something to seriously pay attention to. It is apparent that wealth enables that, but the exact mechanics remain unclear. Why does a hobo having wealth convince a bystander that the hobo should be listened to? What's the difference between a hobo that rolls up in a Rolls Royce and a hobo that rolls up in a shopping cart that changes how others behave?

It may not be complicated, but that doesn't mean I understand it without an explanation.
