Exactly, the voting system will never fix the imbalances caused by concentration of capital, especially when only a handful of people have control of social and mass media, publishing and cultural industries. Not to mention how many NGOs funded by billionaires influence politics. They who have control of information, also have control over ideology.
Good mention of Vargas dictatorship. People don’t discuss Vargas dictatorship as much as the 1964 dictatorship (part of operation condor), but both were very brutal against communists.
