Slum in Rio - Rocinha
Rocinha is a slum in Rio that is extremely well-developed. There are 150,000 - 300,000 people living there and almost all buildings have water, basic sanitation, electricity, etc. - even cable television. Unforunately, Rocinha is also home to many drug dealers. Should Brazil occupy and control this slum? "The preparations to enter Rocinha, a hillside community of more than 80,000 people that has a thriving assortment of businesses and an emerging tourism trade, involved months of planning, officials said."
Today, officials entered Rocinha to assert control over the slum in preparation for the 2016 Olympics. "The authorities said the occupation was an effort at the “pacification” of the sprawling slum, or favela, and it was carried out peacefully. " (NYTimes). What will become of this slum? Will it become a city or be incorporated into Rio as a place that is under the control and guidance of the government? Will it be wiped out? What will happen to the lives of so many people who live in this slum?
“Some say it’s good; others say it’s not,” said Nilson Ferreira, 31, a doorman who lives in Vidigal, a slum near Rocinha that was also occupied on Sunday by soldiers and the police. “For me, it’s fine,” said Mr. Ferreira, who watched the police clean an area where drug traffickers had thrown oil to prevent vehicles from passing."
Many of the slums in Rio are dominated by drug dealers. It would be interesting to see how the slums (or if) they could survive with the removal of these dealers.

Fun fact: at one point, Rocinha had a McDonalds. Globalizaiton in the slums!

I witnessed this same phenomenon when I studied abroad in Beijing during the summer of 2007. The government knocked down a lot of dilapidated buildings in which many local people lived and worked in order to "modernize" for the Olympics (propaganda signs conveying this message were hung all around the neighborhood). Obviously these buildings were in desperate need of rehabilitation long before the Olympics.
I'm not surprised that governments want to improve the condition of slums and other run-down areas when they know that a lot of foreign visitors and press are coming to town; it's natural to want to convey a positive image to the world. I just think it's really amazing that a large influx of outsiders to a place is often the impetus for (debatably) positive change and development due to concern about what the outsiders will think of the place, rather than the residents' desires and/or needs.
In short, my question is: why do outsiders' opinions matter more than those of the residents?
