Originally published in 1924, this book contains various explanations and views on the American tax system by the reformer Andrew Mellon. During his 11 years in office as Secretary of the Treasury, he cut income taxes, reduced public spending, and brought an end to the excess profits tax—all while reducing the federal debt left over from World War I. Mellon’s views on taxation expressed within this book have appeared in letters to Committee of Congress and various organizations and individuals, and are used throughout to illustrate his points, whilst also serving to publish them in a compact form, in one volume. The book also includes various tables and documents of scholarly interest.
