Seeing as Alende was long gone when Thatcher was elected, and the conversation I spoke about was Hayek trying to sell Thatcher on the Chilean "miracle" under Pinochet what the bloody hell does Alende have to do with anything ? 

Oh, that's right, absolutely nothing. The Chilean Miracle was Pinochet's doing under Hayek and Milton's advise, and it's collapse and failure was inherent entirely within itself and utterly unrelated and uninfluenced by what came before.
