The Brazilian middle class is very different from the Turkish middle class. In fact they're almost exactly the opposite politically.
In Turkey, they're left-wing, in Brazil they're right wing.
Although the people protesting in Brazil may actually be the children of the middle class who are themselves poorer and more leftist.
That is actually deadly wrong. The middle class of Brazil is fairly balanced, we have many people that become rich, neaveau riche, that do have a conservative background and stuff, we have some intelectual middle class that is pretty leftist, and we have our elite that is is highly conservative.
Many guys on the prostests on the streets are children from the conservative elite or from the neaveau riche elite, but they are not Conservative! Matter of fact, many of them, specially on Rio are moved by strong leftist ideas and many of them have supported Marcelo Freixo on Rio's Mayorial Election.
That is all.
