Largely because of taxes. Brazilian taxes are extremely high. http://www.quantocustaobrasil.com.br/site/downloads/impostos... This table is in Portuguese but it's easy to understand. The second column means the tax percentage of certain product / service. It's published by the union of Ministry of Finance's workers.

That reminds me of a (satirical) development process we have here in Brazil. It's called goHorse Process. The site is entirely in portuguese but with a little translation help you can have fun too.
