What did president roosevelt mean by a square deal and how did he try to achieve it?

By a "square deal," President Roosevelt meant fairness, as he saw the government as an empire, for workers, customers, and big business. To ensure both this and to root out "crookedness," Roosevelt used the Sherman Antitrust Act. He also meant this as the conservation of natural resources, control of corporations, and consumer protection. The Square Deal was President Theodore Roosevelt's domestic program. Roosevelt reflected three basic goals: conservation of natural resources, control of corporations, and consumer protection. These three demands are often referred to as the "three C's" of Roosevelt's Square Deal. Thus, it aimed at helping middle class citizens and involved attacking plutocracy and bad trusts while at the same time protecting business from the most extreme demands of organized labor. A progressive Republican, Roosevelt believed in government action to mitigate social evils, and as president he in 1908 denounced "the representatives of predatory wealth" as guilty of "all forms of iniquity from the oppression of wage workers to unfair and unwholesome methods of crushing competition, and to defrauding the public by stock-jobbing and the manipulation of securities."
