Webb's "The Texas Rangers" (1935) was a pungent and learned treatment of a frontier institution, but is regarded by many modern historians as an apologia for border violence perpetuated by Rangers against Mexican-Americans. The economic domination of the North, through the tariff, Civil War pensions, and patent monopolies, and the development of the centralized economy dominated by 200 major corporations (over the South and West, which contained the largest share of natural resources) was the theme of "Divided We Stand" (1937).
