I am also Brazilian and can tell you that the debt levels of Brazilians are still WAY, but WAY much lower than those of US citizens, who are historically used to having four different credit cards and a terrible culture when it comes to personal savings.
In fact, the great advantage of US citizens is that they are still enjoying the reserve currency status of the USD and cheap imports from Asia, which give them the impression of easy purchasing all over the place with low interest rates (now matter how much debt they have up their necks).
It is obvious, of course, that after the major sporting events of 2014 and 2016 Brazilian prices will undergo some well-needed correction. But do not expect huge falls, because our country is, indeed, growing a lot in terms of wealth and reduced inequality. In the end, real estate will continue to be expensive, particularly in the most sought-after areas, just like what we see in NYC, Paris, Zurich and so on. After all, salaries go up and prices follow that trend...forget about cheap prices in Brazil apart from local food, locally-produced goods like leather and shops in backwater areas.
The Village Mall people will buy Apple stuff in droves no matter how expensive they are; just like the Sao Paulo BMW motorbike store sells the most motorbikes compared to any other BMW store in the world.
