Practically all the great organizations demanded the abolition of national banks, the free coinage of silver, a sufficient issue of government paper money, tariff revision, and a secret ballot (the last was soon realized). Only less commonly demanded were an income tax, taxation of evidence of debt, and government loans on lands. All of these were principles of the two great Alliances (the Northern and the Southern), as were also pure food legislation, abolition of landholding by aliens, reclamation of unused or unearned land grants (to railways, e.g.), and either rigid federal regulation of railways and other means of communication or government ownership thereof. The Southern Alliance put in the forefront a subtreasury scheme according to which cheap loans should be made by government from local sub-treasuries on non-perishable farm products (such as grain and cotton) stored in government warehouses; while the Northern Alliance demanded restriction of the liquor traffic and for (a short time) woman suffrage. Still other issues were a modification of the patent laws (e.g., to prevent the purchase of patents to stifle competition), postal currency exchange, the eight-hour day, inequitable taxation, the single tax on land, trusts, educational qualification for suffrage, direct popular election of federal judges, of senators, and of the president, special-interest lobbying.
