When one considers one’s actions as activism, done for the purpose of creating social, political, or economic change, and not just personal fulfillment, it behooves one to have a “theory of change.” The “anti-capitalist” theory of change holds that solutions to market failures can’tt come from the market (recalling Einstein, “We can’t solve problems by using the same kind of thinking we used when we created them”), and this is hard to square with a “green economy” theory of change, which believes that a capitalist economy can be reformed, through business, into one that is less destructive to people and the environment.
