 In the runup to the campaign, Aberhart promised to increase Albertans' purchasing power by providing monthly dividends to all citizens in the form of non-negotiable "credit certificates".While he did not commit to any specific dividend amount, he cited $20 and, later, $25 per month as reasonable figures.Though he noted that these figures were given "only for illustrative purposes", he repeated them so often that, in the assessment of his biographers David Elliott and Iris Miller, "it would have been impossible for any regular listener not to have gained the impression that Aberhart was promising him $25 a month if Social Credit should come to power."
