I agree that a racist account of 1915 Japan doesn't really say very much about what's going on with Brazil's economy. But I do think it's important to notice that when the BBC is saying something like "Brazilians are always late" there might be more going on than just a lazy culture.
I was hoping someone whose started a business in Brazil would come along and tell me what it's like. I really know nothing about the country.
Brazil is a huge country, with 200M inhabitants, an area as big as the continental US and a diverse population composed of imigrants from all over the world. What we hear from outsiders is almost always based on local and limited experiences (like this one from the BBC, limited to Rio). There's no single "Brazilian culture".
