I've never really understood the economic interest behind having these massive events anyway. I guess there is a lot of money in it but don't most of these facilities end up not being used afterwards? The amount of time and money that goes into the Olympics is staggering.
The rugby world cup apparently generated $6.2 billion for the Japanese last year. many of those stadiums will be white elephants. The same happened here after the 2010 football world cup. Teams were forced to take over the stadiums and move out of their old ones destined to be demolished. Some have been around for 100 years so where is the history as the politicians don't give a toss.
