I will emphasize that, while Salgado was presumably some hard or soft version of a Leftist most of his life–he was apparently declared an enemy of the State in the late 1960’s in Brazil–that the very real problems he documented were, in almost all cases, the result of groups of people attempting to put Communist ideas into practice.
The Ethiopian famine, for example, was nearly entirely the result of Communist efforts to remake the economic order, as executed by worthless and amoral intellectuals who knew nothing about anything. But they had guns, and power comes from the barrel of a gun. So too does mass death.
All this misery, all this death: the sources can be traced and tracked. Their roots can be known. Their causes can be addressed and extinguished. But only if we dedicate ourselves to the task of thinking clearly and practically.
And rereading Peter Bauer, Friedrich Hayek and others, and fighting left wing intellectuals everywhere they creep into the room.
