I don't know why Marvel still focuses only on Rio de Janeiro in Brazil. There are favelas in Rio de Janeiro for a very sad reason, but most of the neighborhoods in that city are luxurious, with houses costing millions of dollars. It is one of the most expensive cities to live in South America, and is home to the largest number of billionaires in South America.
More and more rich neighborhoods are created every year. In Rio de Janeiro even inside the favelas there are expensive parties with expensive drinks and good DJs.
Sorry for congesting the post.
