> Half a century ago, indeed.

Fake news, I hope originating from historical ignorance. Half a century Brazil was under a fascist military regime: not only was there state violence, torture and heavy censorship (schools and uni's were amongst the main targets) all over, but public education was worst by a lot of metrics including child illiteracy and access to basic education and pre-education. Also they put the children through all sorts of ridiculous parades and bullshit. Truly despicable.
