It seems to be about loss, severe material loss and also loss of hope.
Something is pouring out of his pockets like a river and joining a river that is already flowing. And not a pleasant, scenic river, either, but a river that shouldn’t be there, that is in the wrong place, inside a building, which ought to be secure against such outflows. He is wearing a business suit; clearly he was not prepared to be caught in the middle of this flood. His look is of dark, helpless rage and despair.
I think this is how a great many people must have felt starting in September of 2008: as if their wealth, whether great or small, were pouring out of their pockets like water and going down the drain. There have, of course, been other such times in modern history.
I’m basing this on a small reproduction. I don’t know if I would see it differently if I could see the actual work of art.
