Grant claims that the members of contemporary American Protestant society who could trace their ancestry back to Colonial times were being out-bred by immigrant and "inferior" racial stocks. Grant reasons that the United States has always been a Nordic country, consisting of Nordic immigrants from England, Scotland, and the Netherlands in Colonial times and of Nordic immigrants from Ireland and Germany in later times. Grant feels that certain parts of Europe were underdeveloped and a source of racial stocks unqualified for the Nordic political structure of the U.S. Grant is also interested in the impact of the expansion of U.S. Black population into the urban areas of the North.
