I think just talking about only hard work being a means to success is a over-simplification of working of this complex world. Working smart as opposed to working hard is also important if you want to benefit financially. Lets say a kid works hard in his college days and gets to be a dentist or a lawyer or somebody like that. Lets say another kid in similar circumstances chooses not to work that hard or makes a bad judgement and ends up in a not so rewarding area- rank and file job. It is totally fathomable that the dentist kid could end up making twice as much by working half as hard as the rank and file kid for the rest of their lives. All in all, the idea that working harder will reward you in the future seem fair or karmic. The real world probably is not that simple. I would think there are many other equally important factors like opportunities, luck, judgement etc.
