Don't worry, I'm in total agreement with you, but the original question was about ATC services, hence my comments.
The whole aviation infrastructure here is suffering from lack of investment and planning, and many decisions are for political advantage instead of safety. Have you seen the state of the runway at Porto Alegre recently? They have a beautiful new terminal, but landing would be easier on a dirt strip. The promised Cat III ILS at Curitiba hasn't happened, the restrictions imposed on Congonhas after the accident have been quietly dropped (press release usually on Sunday at 1700....football time) and the airspace working group has made a few cosmetic changes to airways.
Brazil isn't serious about aviation, as varigflier says. The head of ANAC is a political appointee, not a professional from the world of aviation, so he owes his position to those who appointed him and not to the benefit of the country. Long term planning doesn't exist, the far horizon is the next election, and EVERYTHING is geared to getting re-elected. If a project is not highly visible it isn't going to happen, and aviation infrastructure isn't going to buy votes in poor rural areas.

BTW, it was an ATR of Pantanal that skidded off at Congonhas.
