Thomas Hart Benton believed that gratuitous land grants to actual settlers was better public policy than selling land to the highest bidder. As a senator from Missouri in the 1820s, he fought for a system of graduated land prices and donations to destitute settlers. Benton argued that cultivation of land generated far more revenue for the government through duties on imports than direct sales of land. He cited examples from other nations and colonies that had systems of generous land distribution to promote settlement. Benton worked to reform federal land policy to be more favorable to the interests of western states.
