From what I understand, hosting the Olympics has never really been a winning proposition for any city.
A great example of ‘losing’ on the host-job...would be the 2004 Greece Olympics.
If you go into Athens, the airport was built in the 2001 to 2004 period. While two-billion Euro was spent on the airport...you have to figure that roughly a quarter of that went to corruption or fake work.
The ultra-modern subway from the airport into the city? Same deal.
Probably two-thirds of the venues built for the Athens Olympics lay there today....with no real use.
