The origin myth's omissions are grotesque. It ignores three major pillars of our nationhood: genocide, enslavement and imperialist expansion. The massive extermination of indigenous peoples provided our land base; the enslavement of African labor made our economic growth possible; and the seizure of half of Mexico by war (or threat of renewed war) extended this nation's boundaries north to the Pacific and south to the Rio Grande. Such are the foundation stones of the United States, within an economic system that made this country the first in world history to be born capitalist.
