Why do we pursue improving impact investing?

As I read the various books and ideas and learn from my fellow members of the impact investing community, I am increasingly aware that we must fundamentally challenge our premise that the lens from which we operate is based in any form of organizing our economy such as "capitalism" or "socialism" or any other framework, and to recognize that the cognitive leap required is a new way of understanding what the economy is as a tool in the context of revaluating human purpose and our relationship to earth and our future. In other words, from the notions of "saving the earth" or "saving civilization" or "evolving humanity" there is something deeper beyond that. For simply "saving" earth so that the human enterprise can continue begs the question - continue for what purpose?
