Despite the enthusiasm for the purchasing power of the Brazilian middle class, there must be some serious thinking about how it manages this power and effectively manages its financial life. The alert was given by Professor Samy Dana, in his column Caro Dinheiro in the newspaper Folha de São Paulo.According to him, the population's level of debt and installments has increased and families still find themselves pressured by high interest rates. In order to conduct Brazil down a good path, it is pointless to have a middle class with power and willingness to buy if it becomes a big nation of indebted, he said.The analysis is based on research released recently by Serasa Experian and Instituto Data Popular, whose data indicates that the Brazilian middle class alone would be the 18^th nation in the world in consumption.  The 2014 projected expenditures for this nation expects the purchase of 6.5 million TV sets, 4.5 million tablets, 3.9 million smartphones and 3.2 million new cars, for example.  Samy also mentioned another study, by the National Confederation of Goods, Services and Tourism Trade, which reveals that 63.4% of Brazilians, regardless of social class, say they are in debt. The index was 60.2% in January 2013.According to him, this fact should not be seen as necessarily a bad thing, since default rates have even decreased. However, it takes attention and discernment, since the limit is subtle, almost imperceptible, he advised.Please click here and learn more (in Portuguese).
