Communism

On friday, we learned about the history behind the novel. I also asked a question about why America intervened in Latin America, and I still do not understand why they did. At the time America invaded, the Latin American president was trying raise minimum wages. I do not understand why America had a problem with this. I think that for a communist regime, this was rather progressive. I understand America had a containment policy but this seems a little extreme to me. Maybe my classmates can answer my question.
