Being native to that country, I'd say it is possible from the climate point of view (with the exception of southern Brazil). It will not likely solve the terrible and corrupt government we have in place. Brazilians have been dealing with corruption for many decades, only a complete overhaul of that system, may give them a fighting chance.
Growing up being more afraid of the police than the criminals, you sort of tend to loose faith in the government. I could go on and on about this, but it seems pointless quite frankly.
