A building is on fire. The fire seems to be climbing upwards.
[green, in a window close to the fire] What the hell dude. Did you set our entire building on fire? We will both die…
[orange, pouring something on the flames, from higher up] Yeah but I’m higher up in the building so the fire will kill you first. Triggered, liberal?
It’s a general purpose allegory, doesn’t have to be about the US specifically. In my home country (France), the person enjoying the fire tends to be higher up the building, as here the richer people are, the further right they lean. You could also have it be about global warming, about race relations, about queers and other minorities, or pretty much anything else.
