The International Olympic Committee and local Olympic organizers promised that the 2016 Rio de Janeiro Olympics would change the South American city. Almost all the promises were broken despite Brazil spending at least $13 billion to organize the games, with some estimates suggesting $20 billion. The Olympics turned into lucrative real estate deals for several billionaire developers. It did manage to drive the construction of a $3 billion metro-line extension, but estimates say it cost 25% more than it should have. Mostly the Rio games were scarred by scandals and left a city, starkly divided by rich and poor, pretty much as it was with a few cosmetic changes.
