Are Cities Smartening Up About the Olympics?

Not the most efficient use of resources. 

After multiple cities have removed their bid for the 2022 Winter Olympics the organizers are having a tough time selling the event.  Why are potential host cities reluctant?  They have finally figured out that massive projects built for one-time use is a big waste of scarce resources.

Regarding the Olympics The Guardian reports:

It's blisteringly expensive to put together, doesn't improve infrastructure as much as anybody claims and will almost certainly leave a wonky legacy of deserted ski-jumps and bobsleigh tracks littered around the host city.

We can hope this small show of constraint on the part of event organizers, sponsors and politicians is a building block for sanity.  Barring taxpayer funds entirely from supporting the Olympics would be a nice culmination.  The world doesn't need more unused cement ditches.
