How did teddy roosevelt view big business and trust?

Although building his public persona as a  "Trust Buster," Teddy Roosevelt felt that companies could grow large, as long as they did not use unfair practices.

Explanation:

Teddy Roosevelt was sympathetic to both labor and business. The point for T. Roosevelt was that the power of the people should be above the power of the biggest businesses or "trusts" as the biggest conglomerations like Standard Oil and the Rockefellers or US Steel and JP Morgan and the Carnegie legacy were referred to in the day. Thus, the power of the people is embodied in the government, and so government should enforce a "rule of reason" on business.  T. Roosevelt felt a big business firm should be allowed to grow, but there needed to be checks and oversight so that large corporations with a lot of power did not use any unfair practices against the people. At the time, the Democrats accused Roosevelt of taking the side of business in order to gain campaign funds.
