This guy, in my opinion, is the greatest president to ever live, but no one really knows about him. Coolidge allowed for the Roaring Twenties to happen. He hated regulations and one biographer stated "The regulatory state under Coolidge was thin to the point of invisibility." He also understood state and federal government rights: He believed taxes should be lowered and fewer people had to pay them, and he did just that with The Revenue Act of 1924, and there was more Acts in 26 and 28. He was also able to spend less and got rid of 1/4 of the federal debt. State and local governments saw great increases in tax revenue that surpassed the federal budget. He was not an isolationist but he didn't approve of overseas affairs. Calvin Coolidge - Wikipedia, the free encyclopedia It makes sense to look at the times of greatest economic growth and see how it happened. The 20s became the roaring twenties and Coolidge played a huge part by shrinking government and lowering taxes. He really should be the model for the republican party, he is better reagan for damn sure.
