Olympics or bust

I was listening to the latest news about the Olympics and I couldn't help but wonder, why we have had such an outcry for more space to build houses? When all of a sudden we can find the space and money to build an Olympic village with all its amenities doesn't it seem a bit strange? We are spending billions ( cost still rising) on something that will not be used to its fullest after the games. We haven't seemed to have learned from other counties what happened after the Olympics and how much its still costing them. Will it cost us more in the long term? who knows? who really cares? I will probably among the thousands that will watch it.
