Americanization having its roots in political ideals cannot be achieved so long as these ideals, as interpreted by the sources of authority in America, mean one thing for the native-born and another thing for the foreign-born; one thing for men and another for women; one thing for employers and another for employees; one thing for the rich and another for the poor; one thing in one State and another thing in an adjoining State. No American who hopes for national unity can spend too much time insisting upon the most painstaking interpretation of the guarantees of American law, even though it takes him into such technical matters as interpreter service, cost of appeals, discriminatory laws, and race prejudices. Every support of a sound Americanism is strong or weak according as justice is done or not done.
