The men you mentioned were inventors who worked constantly on their creations and had many traumas and difficulties that Keith Olbermann did not suffer.

For instance, the Wright boy's father was a Bishop in the church and moved them a dozen times during their youth. It's hard to make friends when you move every year. He moved them again weeks before one of the boy's high school graduation, leaving him without a high school degree. One of the two who was very athletic got his front teeth knocked out playing sports and became withdrawn and housebound, dashing his plans to attend Yale. Instead, he spent the next few years at home, caring for his mother, who was terminally ill with tuberculosis. However, the rest of their life was full with building printing presses, building bicycles, running a bicycle shop and inventing and perfecting numerous aircraft.

Nikola T. had a similar life with intense work and study and invention while being backstabbed and financially destroyed while he tried to bring free energy to the masses, leaving him in the end with only enough money to live in a tiny walkup, living a sparse and lonely solitary life.

Keith Olbermann has lived a life of luxury and importance in contrast. Not really a good comparison.
