Contrary to conventional wisdom, ideas and faith are what make the world go around.
Money just greases the axle.
Idealism is the strength of the world's religions, the impetus for historical movements like the emergence of Communism and democracy, and the moral foundation of nations. Ideas move men. Neither facts nor pragmatic considerations have the same power. Man seeks a link to eternity through what he perceives as truths that transcend the limits of his own finiteness. Peace is such an ideal.
