Buddhadāsa Bhikkhu coined the phrase Dhammic socialism. He believed that Socialism is a natural state meaning all things exist together in one system:
Look at the birds: we will see that they eat only as much food as their stomachs can hold. They cannot take more than that; they don't have granaries. Look down at the ants and insects: that is all they can do. Look at the trees: trees imbibe only as much nourishment and water as the trunk can hold, and cannot take in any more than that. Therefore a system in which people cannot encroach on each other's rights or plunder their possessions is in accordance with nature and occurs naturally, and that is how it has become a society continued to be one, until trees became abundant, animals became abundant, and eventually human beings became abundant in the world. The freedom to hoard was tightly controlled by nature in the form of natural socialism.
Han Yong-un felt that equality was one of the main principles of Buddhism. In an interview published in 1931, Yong-un spoke of his desire to explore Buddhist Socialism:
I am recently planning to write about Buddhist socialism. Just like there is Christian socialism as a system of ideas in Christianity, there must be also Buddhist socialism in Buddhism.
Of all the modern economic theories, the economic system of Marxism is founded on moral principles, while capitalism is concerned only with gain and profitability.... The failure of the regime in the former Soviet Union was, for me, not the failure of Marxism but the failure of totalitarianism. For this reason I still think of myself as half-Marxist, half-Buddhist.
