In 1924 Hargrave was introduced to the economic theory of Social Credit, the creation of C. H. Douglas. Hargrave took up the creed with fervour, attracted by its seemingly-scientific 'truth' and its sense of mission. Social Credit changed Hargrave's belief in the reformed individual as the key to a better society: the key was actually, he now believed, a reformed economic system. By the late 1920s he had re-purposed the Kindred to be a 'megaphone' for social credit, bringing the esoteric economic theory to the public at large.
