The controversy about whether Olympics are a waste of money becomes a focus every time after a term. I saw an article says there are only 2 host countries made profit from Olympics which are 1988 Seoul Olympics and 1992 Barcelona Olympics after 1980. Seoul made profit of US $300million, US $5 million for Barcelona. So, what about 2008 China Beijing Olympics, how much Chinese government spent on Olympics? Just wait a moment, let me clear my throat. The answer is $42bn according to Wall street Journal’s report. However, China official announced US$2.3bn. It has a massive gap between these two figures. Somehow it still is a huge figure for either of them. I am not going to focus on which figure is more accurate, let’s put this aside first. My attention is to if Olympics are so expensive, why countries are still bidding for hosting the Olympics?
