Capitalism is the extraordinary belief that the nastiest of men, for the nastiest of reasons, will somehow work for the benefit of us all.
Behind the line
What it means
Our interpretation.
The speaker mocks capitalism as a strangely hopeful faith: that people motivated by the worst impulses, such as greed, will nevertheless end up producing benefits for everyone. The word "extraordinary" carries the irony, suggesting the theory asks for more trust in selfish motives than seems reasonable.
