Not to strain this metaphor to the breaking point, but guy A is, in theory, a representative of guys C-ZZZZZZ, and they have recourse when they're angry at his actions. More importantly, guy A IS being held accountable; there's a lot of anger at the government as well over the bank bailouts (and the attendant lack of conditional guarantees). even in the situation you're describing, of COURSE one would blame guy B (along with guy A). Coincidentally enough...that's exactly what's happening.
