I am speaking in reference to charity (self-less love (agape)) and the vow of poverty practiced by those in holy orders and consecrated laity. "the rate of increase of his wealth" only tells you how good he is at increasing wealth with little indication in why he is increasing his wealth, its shallow. It tells you nothing about the man other than that he is able to increase his wealth by some metric. A man who is willing to sacrifice mammon however or increase mammon for the sake of another, instead of being oriented around mammon for the sake of mammon, that is someone oriented toward Christ, even if they do not know Him by name. And if you believe Christ to be the Alpha and Omega, such a man will share, in a condescended manner, with those divine attributes of God, thus attributes that the eye cannot see, ear has not heard or the heart of man conceived will be allotted to him. It "tells much more" than the capacity to increase wealth.
