The policy that favored people born in the United States during the early 1800s was called the American System.
The American System was an economic plan that played a major role in American policy during the first half of the 19th century.
The plan consisted of three important parts: a tariff to protect and foster American industry; a national bank to boost commerce; and federal subsidies for roads, canals, and other 'internal improvements' to develop profitable markets for agriculture."
