The Ringer:

Only a handful of cities can afford the two-week-long, über-expensive bonanza. Unless something changes, angry citizens who don’t want to pay for a bunch of useless stadiums are going to force the IOC to decide on a semi-permanent set of hosts.

I’d be sad to see the Olympics disappear but it would make economic sense if they did. They don’t provide nearly the benefits the IOC or organizing committees promise. There’s been talk the last few years of having a “permanent host city” (Vancouver comes up often because of it’s existing infrastructure and suitable weather for both Summer and Winter Olympics) or to even do one of the suggestions in the article – separate events in separate cities.
