Whom did Pinochet openly favour in Chile?
Augusto Pinochet, dictator of Chile from 1974-1990, was a former general who favored business interests after deposing Allende with US assistance, as his support feared a Communist presence gaining a foothold in Central America, similar to Castro in Cuba. Nationalism efforts were initially successful but increased consumer power and, as a result, caused rising prices and public discontent, leading to Pinochet's army coup.
After Allende reportedly committed suicide in defense of the palace, Pinochet took power. He promptly ended democratic rule in Chile, concluding 46 years of rule by the people. Despite presiding over robust economic growth, he was accused on numerous human rights violations during his tenure of favoring a right wing minority system. His involvement in Operation Condor also sought to undermine leftist groups throughout South America, often through murder. Even after ending direct rule, his position as commander and chief of the army allowed influence over democratic proceedings for several more years: "He set limits, for example, on economic policy debates with frequent warnings that he would not tolerate a return to statist measures, and he blocked virtually all attempts to prosecute members of his security forces for human rights abuses. Through intimidation and legal obstacles, General Pinochet sought to ensure his own immunity from accountability." More than any one thing, it would seem that Augusto Pinochet favored himself first and foremost, and in avoiding prosecution until shortly before his death, he was largely successful.
The end results do show that he was ultimately his own undoing, as revelations of his secret foreign bank accounts alienated even his closest supporters. If nothing else, totalitarianist groups can only maintain power through total control. Without enough support, one is doomed to fail if subject to the excesses that power often brings.
