Totalitaria corporatocracy

Corporatocracy. When the Government is controlled or influenced by corporations. In the last century and a half; corporacratic states have risen and fallen: examples include the Banana Republic, Rhodesia and especially the now famous East India Company. With these corporacratic states, 2 things are common with them.

First: they were oppressive to the native population such as the banana massacre in 1928 by the Colombian military or the 1954 coup d'etat to ensure mass profit of fruits like bananas for the businessmen of the United Fruit Company. Meanwhile in Rhodesia apartheid was implemented (although it was to a lesser extent than South Africa's apartheid) whilst they collected the diamond reserves. And then there's the East India Company whose heavy taxes led to the Great Bengal Famine of 1770 costing the lives of between 7 - 10 million, a third of Bengal's Population at the time.

Second, almost all corporacratic states (companies) are government-controlled or influenced. This was such the case as the British controlled The East India Company along with Rhodesia whilst United Fruit, Standard Fruit Company (etc, etc.) was influenced by the US*. But what if this second clause is somewhat annulled? What if corporatocracy was not controlled by government? What if there was a corporatocracy where nothing could prevent its ambitions?
