It is a fallacy to believe that businesses operate efficiently simply because there is a profit motive. Businesses are complex organizations made up of people, with all their failings and weaknesses (if you want to call them that). It is not necessary for a business to be perfectly efficient to survive, it is only necessary that its competitors be equally inefficient. I like to point this out to anyone who says "well, a business wouldn't do it if it made them less efficient", eg the case of open floor plans for programmers: https://news.ycombinator.com/item?id=7507280 https://news.ycombinator.com/item?id=7507280
