Yes, but what you are talking about is Social Darwinism..
The term "Social Darwinism" is most closely associated with the writings of Herbert Spencer (who coined the phrase "survival of the fittest") and William Graham Sumner. Regardless of how scholars of Spencer interpret his relation to Darwin, Spencer proved to be an incredibly popular figure in the 1870s, particularly in the United States. Authors such as Edward Youmans, William Graham Sumner, John Fiske, John W. Burgess, and other thinkers of the gilded age all developed theories of Social Darwinism as a result of their exposure to Spencer (as well as Darwin).
Social Darwinism enjoyed widespread popularity in some European circles, particularly among ruling elites during the late 19th and early 20th centuries. During this period the global recession of the 1870s encouraged a view of the world which saw societies or nations in competition with one another for survival in a hostile world. This attitude encouraged increasing militarization and the division of the world into colonial spheres of influence. The interpretation of Social Darwinism then emphasized competition between species and races rather than cooperation. In the time since then, evolutionary theory has de-emphasized inter-species competition as well as the importance of violent confrontation in general. Advances in both the social and natural sciences, therefore, have discredited many of the assumptions on which Social Darwinist theories were built.
