Seems clear enough to me. The author returns again and again to the idea that the men are "responsible" for the coming black swan event they are preparing for. They are but small men in a wider world whatever their wealth.

Such an idea is ridiculous particularly considering the event hasn't happened and is unknown.

It is sad how little the group appears to care about their fellow men. Perhaps that's the lens of the author, I don't know.

But the author also strongly links survival thinking with selfishness, which is hogwash. Poor article, snatching ideological defeat from the jaws of victory.
