In their defence, it is a difficult concept to grasp. My dad started his career shovelling gravel for a few dollars an hour. Now he's a vice president making very good money. In his mind, anyone can replicate what he did by working hard instead of being lazy and asking for handouts.
I eventually got through to him one day when he was talking about hiring for a senior management position. He was interviewing all these people with fancy degrees and credentials. I asked why not promote one of his hard workers? He laughed and said the person needs to be more than a hard worker to manage multi-million dollar projects. But where would he be now if his old boss had thought the same thing? My dad has none of the credentials of the people he was interviewing. He'd still be shovelling gravel 60 hours a week for minimum wage if nobody gave him the opportunity to advance. How could he think hard work will be rewarded when he doesn't even reward it himself? That's when he admitted the world works differently now.
