It may surprise you to know that the public transport buses in Brazil each have a turnstile and a very narrow one at that. (Based on personal experience).
Another surprise might be to learn how the mass protests got started. Look no further than the strapline which is one of the slogans of the Free Fare Movement a small group that campaigns for free public transport, which incidentally already occurs in some cities across the world including a smattering in the UK. The group of young activists have admitted to being more than a little surprised themselves at the outpouring of frustration and dissatisfaction, with the government, that their protest over a public transport hike sparked across Brazil.
The next surprise was that within a couple of weeks the group had the ear of the President and the people had the promise of a referendum on political reform.
Lets hope that this is a watershed and Brazil and its people have begun to change the endemic culture of corruption.
