Mr. Kahn's rebuke to those noxious demagogues who try to aid Germany and hurt America by prattling about this being "a rich man's war" is rendered all the stronger because he insists on heavy progressive taxation of incomes and profits for war purposes. This taxation should go up to, but under no circumstances go in the slightest degree beyond, the line at which it interferes with or limits production or prevents the fullest development of our business resources during the war. We need to speed up production to the very top limit. While this war lasts we have a right to demand of every man, whether capitalist, or labourer, or farmer, that his prime effort and motive be to win the war, for this is the people's war, America's war--the war of all of us. The Government should see that every man does his full part. Therefore it should see that the rich man does his full part. Therefore, not merely in his interest but in the national interest, it should also see that no frantic extremist, under the plea of forcing the rich man to do his full part, renders it impossible for him to do anything at all. So to act would bring lasting damage to the community, and, whether intentionally or unintentionally, would create a condition which would bring the war to a standstill. This is a capital study of the problems which are of vital interest at this moment to all Americans who love their country, and who wish while serving their country also to serve all the free nations of civilized mankind. THEODORE ROOSEVELT. _Sagamore Hill_, _June_ 15, 1918. FOREWORD This book should be in every man's home; every woman should read it. It is a pity that it is not in every German's home. But before your ordinary man can grasp its full significance, it is as well that he should know something of the man who wrote it, and still more why he wrote it. Mr. Otto H. Kahn, one of the leading financiers of America, and widely renowned for his manifold charities, his strenuous public life, and his generous patronage of the Arts, is of German blood and was born in Germany. But, from his great-grandparents, who were French Alsatians, he inherited a great love of France. His father, after taking part in the German Revolution of 1848, fled to America, became naturalized as an American citizen, and finally returned to Germany after ten years of banishment. From this father, Kahn inherited the love of liberty.
