As shown consistently by economists, Olympic Games are a vanity project that wastes public resources, scarce public resources. In this case, South Korea's swift decision to demolish (https://www.aol.com/article/news/2018/02/22/south-korea-plans-to-demolish-newly-built-olympic-stadium/23368450/) its flagship Olympic stadium is a welcome case of cutting the future costs of maintaining the White Elephant. Or, in terminology of VUCA management: an act of avoiding the sunk cost fallacy.

In the mean time, make sure you know your stance should your city/country attempt to bid for the next Olympic Waste.
