I'm sure it doesn't come close to the markup on the console, but what is a typical cost of living figure like in Brazil?
That's a difficult question. I'll try to answer to the best of my capacity.
First, income.
Brazil's federal institute for geography and statistics, IBGE, which is really professional and respected, published what I believe is an accurate survey of income (among many other metrics) in 2012. According to p. 204, 13.7% of respondents made 3x the minimum wage or more, which at the time was R$622,00 - that was roughly US$300 at the exchange rate of the time (1 US dollar = ~2.05 reais). So that means that roughly 7% of the population made US$900 or more a month. The labor laws in Brazil establish that every year, every salaried worker works 11 months (1 month vacation) and is paid 13 salaries (a mandatory bonus, usually paid in December). At US$900 a month, a worker would make US$11,700 a year. Since we're roughly ~200m people, some ~27.4m make that in a year.
Second, cost of living.
DIEESE, a non-governmental organization, calculates and publishes the "ideal" minimum wage (the official minimum wage is far from ideal) every month. For June of 2012, it was R$2,416.38 - US$1178 at the exchange rate back then. I think that's accurate enough, because back then my rent was US$463 a month (2-room modest apartment, I pay all utilities). Healthcare, gasoline and phone cost some US$300. If I only made $900/mo, I'd be just US$137 shy of being broke.
Third, conclusion.
Since median and average income is quite low, companies aim for a small part of the market - much, MUCH smaller than those ~27.4m who make more that US$11,700 a year - and charge outrageously high prices. Those who can pay, will buy. And those who can't, will buy too - with their credit cards, at very, VERY high interest rates.
