I think the one person who did the most in history for good, is Jesus Christ not Steve jobs. That is why His economics is the greatest economics. These merchants of the earth where powerful, but not as powerful as Jesus Christ. He wasn't greedy He was selfless. He wasn't a materialist He sought the Father's will not His own.
He not only can supply the stuff, but can give you Eternal Life.
Seeking the stuff is a bad investment, because it rots and decays.
Seeking Christ is sustainable forever.
