Money in the bank isn't working and due to inflation is slowly just disappearing - so that is clearly undesirable. But it doesn't follow that it's a good idea to just spend them on anything, you need to spend them on something with a chance of giving you a return. If you have a division that isn't giving you a return, and you don't see a way of changing that, keeping it around is just a way of making your money disappear faster - which is also clearly undesirable.
