Brazil Olympic stadium used for a parking lot

Vox - Brazil spent about $3 billion building 12 new or heavily refurbished stadiums for last year's World Cup. Officials promised these taxpayer-funded venues would continue to generate revenue for years, hosting concerts, pro soccer games, and other events.

But as Lourdes Garcia-Navarro at NPR reports, most stadiums are failing to generate much revenue at all. The most expensive one, in Brasilia, is most regularly used as a site for a municipal bus parking lot.
