No. They were hardly successful. In fact, there were dirt poor because the education system was reserved for the elite. They may have had the genetics for Banking or Finance but they were force to swing hammers and other tools to survive. No education will do that to you. Lincoln and Einstein were genetic flukes.
Quote from morganist:
Perhaps you could see it another way. The road to success at the time of your ancestor could have been mining but now it is banking. The predisposition in this case could be the financial or social aspect of the job not the job itself. For me banking is an art not a way of making money, although I am not opposed to that. My predisposition to banking was the attraction the way money works and security.
I will always be drawn to money not for a salary but the way that money works. The money does not have to be mine but the process and the way that money works is the attraction to me. This is in my opinion a genetic predetermination.
