This question seems to me to refer to 'external' power and money. In other words, the being in a position of power refers to power over other human beings, such as that of a medieval king, emperor or, in more modern times, a national president or dictator. If this is the case then power and having great wealth often go hand in hand, so the question is valid.
However, if you are talking about power over your own self, the ability to be in complete charge of your own body, mind, emotions at all times, then you are on the way to having REAL power. Such people are obvious to us all, even though not many come along. People like Mahatma Ghandi and Mother Teresa. And if you believe - as I do - people who had no intention of being worshipped but were, after they died, regarded as saints - even gods. The founders of most great religions would fall into this category. Often these people had no money to speak of...but they did have power. This sort of power is infinitely greater than money.
