This is a list of monetary reformers from the past to the present according to several schools of thought. Monetary reformers primarily belong to the following groups: * Supporters of publicly issued money who oppose charging interest on issuance of money, formerly called "Greenbackers" in late 19th century United States, * the Austrian School who generally support a return to the gold standard or full-reserve banking, and * the Post-Keynesian School who generally wish to regulate or reduce leverage and debt in the economy or direct it to "productive, non-speculative" uses.
