Case in point 1: Guatemala of 1953, socialist president Jacobo Arbenz instituted agrarian reforms that undermine the business activities of the United Fruit Company. The company makes financial contributions to the U.S government to stage a coup d'etat that deposes Arbenz and replaces him with a leader who allows the corporations to operate coffee plantations with legal impunity. Clearly, the financial costs associated with the coup were overshadowed by the profits that the corporations gained in the end. America's leading coffee corporations still have hundreds of plantations based in Guatemala where enormous profits are gained by oppressing workers.
Case in point 2: Chile of 1973, Salvador Allende implements land-reform programs that severely undermine the financial success of America's leading corporations including the IBM. The Corporations make a financial contribution to the U.S government that in turn provides the Chilean military with $10 million to subvert Allende. The corporations may have donated far more than $10 million, but by deposing Allende, they stood to make tens of millions.
Case in point 3: U.S corporations that provide military technology profited a great deal from the War and it is possible that they made financial contributions to persuade the Bush Administration to invade Iraq and Afghanistan.
