What does (lack of) wealth have to do with the effectiveness of the treatment? The article mentions that in the US there's enough donated human skin for grafts; that appears not to be the case in Brazil. Until that changes, this appears to be a better solution, and who knows - maybe it turns out to be better in general too (e.g., the article also mentions the prepared grafts can be kept in storage for up to 2 years).
