People with an attitude of entitlement are a drain on the world. A net negative.
I know someone like this. She believes the world and all those in it exist for her convenience. If she wants someone to go out of their way for her, and they dare say "no", her response is "What are you doing that's so important that you can't?" She believes if someone has something they aren't currently using, she should be able to take it if she wants it. The world revolves around her, and yet she despises people she sees as needing to be the "center of attention".
Of course, this is the same attitude held by most government employees.
