The Progressive utilization theory (PROUT) is a socioeconomic and political philosophy created by the Indian philosopher and spiritual leader Prabhat Ranjan Sarkar. He first conceived of PROUT in 1959. Its proponents (Proutists) claim that it exposes and overcomes the limitations of capitalism, communism and mixed economy.] Since its genesis, PROUT has had an economically progressive approach, aiming to improve social development in the world. It is in line with Sarkar's Neohumanist values which aim to provide "proper care" to every being on the planet, including humans, animals and plants.
