Preposition

This is merely a question, a riddle, an enigma. Who holds the power in this situation. There are two men hailing from two different places knowing two different crafts. There is one man who knows how to make it, has the want and the drive to make it, but is not able to make it. On the other hand you have a man who does not know how to make it, does not want to make it, but is able to make it. Who holds the power. Does the man with the know how force the other to make it. Other does the other man who is able to make it refuse to the utmost and hold all of the cards as hostages. So which is it. The man with the know how, or the man who is able, Or the better question is, is it you?
