Guaranteed minimum income (GMI) (also called minimum income) is a system of social welfare provision that guarantees that all citizens or families have an income sufficient to live on, provided they meet certain conditions. Eligibility is typically determined by citizenship, a means test, and either availability for the labour market or a willingness to perform community services. The primary goal of a guaranteed minimum income is to reduce poverty. If citizenship is the only requirement, the system turns into a universal basic income.
A system of guaranteed minimum income can consist of several elements, most notably:
Basic income means the provision of identical payments from a government to all of its citizens. Guaranteed minimum income is a system of payments (perhaps only one) by a government to citizens who fail to meet one or more means tests. While most modern countries have some form of GMI, a basic income is rare.
The first Muslim caliph, Abu Bakr, introduced a guaranteed minimum standard of income, granting each man, woman, and child ten dirhams annually; this was later increased to twenty dirhams.
In 1795, American revolutionary Thomas Paine advocated a citizen's dividend to all United States citizens as compensation for "loss of his or her natural inheritance, by the introduction of the system of landed property" (Agrarian Justice, 1795).
French Emperor Napoleon Bonaparte echoed Paine's sentiments and commented that 'man is entitled by birthright to a share of the Earth's produce sufficient to fill the needs of his existence' (Herold, 1955).
