Economist HENRY GEORGE (1839-1897) was, at the height of his popularity in the 1880s and 1890s, considered the third most famous American, behind Mark Twain and Thomas Edison, and his liberal philosophies on taxation, copyrights, poverty issues, and more continue to influence progressive movements today. Here, in this 1891 work, George issues a passionate call to Pope Leo XXI to reconsider his public denunciation of the very notions of egalitarianism and opportunity that George had championed throughout his career as an economist. This edition also includes the encyclical letter that inspired George"s anger.
