"Boromir: But it is a gift. A gift to the foes of Mordor. Why not use this Ring? Long has my father, the Steward of Gondor, kept the forces of Mordor at bay. By the blood of our people are your lands kept safe! Give Gondor the weapon of the enemy! Let us use it against him!"

Strider: You cannot wield it. None of us can. The One Ring answers to Sauron alone. It has no other master."

Trying to fight and compete with a system that thrives on greed using its own tools and rules requires the ruthless use of greed to compete, and greed has a way of warping ones' heart to continue forever justifying itself until its host is left an empty husk, having made a barren wasteland of all they hoped to save.

Capital knows its masters, and it will not be wielded by people who would subvert its influence.
