José Mujica

Mujica's administration implemented a range of progressive policies, including the decriminalization of abortion, the legalization of marijuana consumption and the legalization of same-sex marriage. Additional measures strengthened the country's trade unions and significantly bolstered minimum wages.
While in office, Mujica was described as being "the world's poorest president" due to his austere lifestyle and his donation of around 90 percent of his US$12,000 monthly salary to charities that support low-income individuals and small entrepreneurs. He was an outspoken critic of capitalism's focus on stockpiling material possessions which do not contribute to human happiness. Provided by Wikipedia
