The Square Deal was Theodore Roosevelt's domestic policy. It centered on two main principles: The protection of the working and middle classes from corporate excess; The conservation of natural resources for the enjoyment of current and future generations. Roosevelt abhorred the manner in which the common American man was being used for the gain of a tiny minority of Capitalists. Although, the ideas are similar in nature to much of FDRs New Deal policies - the term "Square Deal" should be a dead giveaway that it is referring to Theodore. Although, had Theodore lived to see his kin institue the New Deal, there is no doubt he would have approved.  

Calvin Coolidge believed that America was best served by prioritizing the interests of big business. He ran a Republican government that advocated a hands-off approach towards economic interference. 

The quote is an excerpt from a speech given by Theodore Roosevelt in 1906. The speech is commonly known as “The Man with the Muck-Rake.” Roosevelt was a Progressive politician who argued for the usage of a graduated income tax and the implementation of an inheritance tax to limit the proportion of money that could be handed down from one generation to another.

Ronald Reagan's 1980 Presidential campaign saw a new fusion of various conservative political identities under the Republican banner. In economics, Reagan used his typically limited government view to advocate for lower taxes and less regulation of businesses. Within his first two years in office, he achieved signing a bill that required massive income and business tax cuts.

The presidency of Theodore Roosevelt was notable for being much more progressive than that of his predecessor, William McKinley, whose assasination promoted Roosevelt to the Presidency. Roosevelt promised a "Square Deal" for Americans. Notably, this involved "trust busting," or breaking up monopolies, a large effort to conserve natural resources, and various labor laws.

"Supply-side economics" gained their name from the fact they intended to benefit the suppliers of commercial goods, the businesses and manufacturers who made most of the products in the economy. Supply-side economics is most associated with President Ronald Reagan, who lobbied for massive tax cuts, deregulation of business, and large scale reduction of government spending. During Reagan's eight years in office, he managed to cut taxes, roll back corporate regulations, and slash welfare spending.

The "Labor Movement" was a broad grouping of activists that sought to protect the safety and rights of workers in a variety of working class jobs. Throughout the late-nineteenth century, the full flowering of the Industrial Revolution had produced a widespread manufacturing sector centered on factories that employed children as young as 4, and the work hours were usually between 12 and 15 hours a day, six days a week. The labor movement sought to protect workers' rights in a number of ways, including shortening work hours, eliminating child labor, and unionizing the workforce. Most of all, they stood against the businessmen who owned the factories.
