Both President Coolidge and President Hoover were pro-business Republicans. They believed that any policies that helped big business (such as tax cuts) were good for the economy, and thus, good for America; they opposed government policies that they thought would limit the ability of corporations to make money. For example, both presidents believed government should not regulate corporations. They both adhered to a policy of "laissez-faire capitalism": keep the government out of business, and the result will be prosperity. Of course, as it turned out, that was untrue, and many historians believe laissez-faire policies contributed to the Great Depression. But those policies were definitely something both presidents supported in the 1920s.
