Situation: The 2016 Olympic Games caused a property boom in central favelas (slums) in Rio, such as Vidigal. This place had been ruled by drug gangs but changed due to the Games' potential.

Effects: Land value increased by 300% in three years. Outsiders, real-estate agents, and land speculators moved in, leading to a 165% increase in the average house price between 2012 and 2016.

• Real-World Example: Imagine buying a candy bar for $1 in 2012, and by 2016, you had to pay $2.65 for the same candy!

Downsides: Activists argue that over 170,000 people were displaced from their homes for the Olympic games. Favela do Metro, home to 1,000 residents, was demolished, perhaps to build parking lots.

• Real-World Example: It's like being kicked out of your treehouse because someone decided to build a parking lot for flying cars there.

Occupy Wall Street (OWS): An anti-capitalist protest in New York focusing on economic inequality. Protesters used the slogan "We are the 99 per cent" to highlight the massive profits and disparities created by the financial sector.

• Real-World Example: Imagine a pizza divided into 100 slices. The financial sector takes 99 of these slices, leaving just one for the rest of us!

Occupy St Paul's: A similar protest in London in 2012. Protesters camped outside St Paul's Cathedral after failing to camp outside the London Stock Exchange. The camp lasted until February 2013, resulting in 20 arrests.

• Real-World Example: It's like pitching a tent in your school playground to protest against the unfair distribution of homework!
