I absolutely agree that power is attractive. I know that you need hard data to back it up, but power attracts many people. Look at TV shows like House of Cards or Game of Thornes as an example. Power fascinates us. People dream about, covet, admire and submit to power. Even before the concept of money existed, the fight to control land, other tribes and other people has always overwhelmed us, and for many, developing a relationship with someone with that power would be a highly sought after quality. It promises safety, it feeds our ego, it fulfills the dream of rising above the rest, where it be through inheritance or marriage.
