In 1964 the US supported General Branco's Junta in Brazil, selling government firms and throwing the country open to foreign companies. With democracy and free speech supposedly still in place, massive student protests took place in 1968. The junta responded with military clamp-down, killings, and torture. The Ford Motor Corporation and GM funded private police/torture squads in Brazil to patrol their factories, violently removing unionist agitators. Amidst the killings, Friedman declared Brazil an 'economic miracle.'
Lesson learned: Market reforms would lead to vocal and widespread protest.
