One way to have the government control "the trusts" was to require
corporations doing business across state lines to obtain their charter from the federal
government, not one of the states. Theodore Roosevelt supported this idea of federal
incorporation while he was President.
Federal incorporation appealed to President Roosevelt because it seemed to give the
executive branch the necessary power to regulate business in the public interest.
Federal incorporation promised to remove the trust issue from immediate partisan
politics. By giving corporations prior government approval of mergers, federal
incorporation would enable them to grow with assurances that at some later date a
politically motivated President might not prosecute them under the Sherman Act.
Federal incorporation seemed to provide for
the prevention of stock market abuses
making the government the arbiter of corporate combinations and growth
to assure enough competition to encourage efficiency and innovation
to assure enough competition to provide for fair prices and reasonable profits.
