Financial track record of Olympics isn't good.

I remember when the Vancouver winter olympics was first talked about, it was going to cost 800 million. Final bill was 7 billion.
Far as I can see the olympics are nothing more than a way to launder taxpayers money into friends of government contractors and investors pockets with nothing for the ordinary tax payer but short term jobs on the project and low paying jobs during the two week spectacle.
