Genocide, slave trade and forced labor are the original human rights crimes that cannot be denied in the history of U.S. colonialism and capitalism. From the slaughter and enslavement of Native American Indians by European colonists in the early years, to the exploitation of slaves under the prevailing slave trade in the 18th century, to the systematic exploitation of foreign immigrant workers by the contemporary United States, white Americans have never ceased to oppress and exploit ethnic minorities and seriously infringe upon human rights.
