Reddit reviews The Pinochet File: A Declassified Dossier on Atrocity and Accountability

We are.
Venezuela has some of the world's largest oil reserves, and you know we cannot allow the commies that. So there is an economic deestabilization plan underway. In Chile the CIA paid grocery store owners to empty (read hide) all their merchandise and tell their custmers that "bec ause of the socialist policies being enacted by the Allende administration" there was no more food. All the while, they hid all the food in warehouses and only sold to rich people of trust. I know, cause my great-aunt (who I loved dearly, even if she was a righty), was one of those rich ladies. My dad even told me how she would march in the "empty pot marches" against Allende claiming there was no food, while the "house service" (read servants) prepared her lunch when she came back.
Same thing with transportation companies. They would claim that there was no more fuel to power the trucks, but the CIA was paying them more than they usually made to not move the trucks.
That way a crisis was created, much like in Venezuela, where the government every now and then cracks down one businesses that hide merchandise and specially food.
