Aside from financial gains through tourism etc. I have another observation from the 1972 Olympic Games here in Munich: Hosting the Olympic Games was a booster for infrastructure projects. Like some new roads, finally deciding to build an underground, building a suburban sub-surfsce rail line through the city center and convert it to pedestrian area, ...

Multiple of those projects where pushed off before, but Olympics gave the "let's do it" spirit for those huge projects.

Having those projects done is an important part of today's quality of life here (while since the late 90ies underground construction mostly stopped and we're seeing consequences as the city grows ...)
