We must have complete and effective publicity of corporate affairs, so that the people may know beyond peradventure whether the corporations obey the law and whether their management entitles them to the confidence of the public.

Corporate expenditures for political purposes, and especially such expenditures by public-service corporations, have supplied one of the principal sources of corruption in our political affairs.
