Context: We wish to control big business so as to secure among other things good wages for the wage-workers and reasonable prices for the consumers. Wherever in any business the prosperity of the businessman is obtained by lowering the wages of his workmen and charging an excessive price to the consumers we wish to interfere and stop such practices. We will not submit to that kind of prosperity any more than we will submit to prosperity obtained by swindling investors or getting unfair advantages over business rivals.
