It's only made worse by how only select people can participate. That is on top of Brazil's history of using literacy tests for racial discriminatation. As well as their current, ineffective mass-incarceration policy (now 3rd largest in the world), which as in the US hits indigenous and black south americans harder. I don't expect they'll have a rich corpus of indigenous literature either.
This is why I am very critical, despite reading a book generally hurting nobody. If they truly wanted to keep people out of prison they should end their mass incarceration and improve inequality, not allow select people (who will be almost definitely be disproportionately white) to get out easier.
But then again the head of state is an outspoken fan of the military dictatorship so that does not seem likely.
