Have you ever thought that most money in the world is spent inefficiently? All money in the public domain (government, schools, hospitals, non-profit organizations etc) and companies (the bigger the company, the less optimal are the acquisitions) could be spent more efficiently if the buyers wanted so. However, the buyers (i.e., the employees who spend the money) are not incentivised to spend the money well when it's not their money. Put simply, when people don't have their skin in the game, they make suboptimal decisions. To get deeper arguments, watch the video.
