Anarcho-primitivists often criticize mainstream socialism for supporting civilization and modern technology which they believe are inherently based on domination and exploitation. They instead advocate the process of rewilding or reconnecting with the natural environment. Veganarchism is the political philosophy of veganism (more specifically animal liberation) and green anarchism. This encompasses viewing the state as unnecessary and harmful to both human and animals whilst practising a vegan diet. Georgism is an economic philosophy and ideology which holds that people own what they create, but that things found in nature, most importantly land, belong equally to all. The Georgist philosophy is based on the writings of the economist Henry George (1839–1897) and is usually associated with the idea of a single tax on the value of land. His most famous work is "Progress and Poverty" (1879), a treatise on inequality, the cyclic nature of industrialized economies and the use of the land value tax as a remedy. Georgists argue that a tax on land value is economically efficient, fair and equitable; and that it can generate sufficient revenue so that other taxes (e.g. taxes on profits, sales or income), which are less fair and efficient, can be reduced or eliminated. A tax on land value has been described by many as a progressive tax since it would be paid primarily by the wealthy and would reduce economic inequality. Georgist ideas heavily influenced the politics of the early 20th century. Political parties that were formed based on Georgist ideas include the Commonwealth Land Party, the Justice Party of Denmark, the Henry George Justice Party and the Single Tax League. Several communities were also initiated with Georgist principles during the height of the philosophy's popularity. Two such communities that still exist are Arden, Delaware, which was founded in 1900 by Frank Stephens and Will Price; and Fairhope, Alabama, which was founded in 1894 by the auspices of the Fairhope Single Tax Corporation. Christian anarchist Leo Tolstoy was enthused by the economic thinking of Henry George, incorporating it approvingly into later works such as "Resurrection", the book that played a major factor in his excommunication. Guild socialism is a political movement advocating workers' control of industry through the medium of trade-related guilds "in an implied contractual relationship with the public". It originated in the United Kingdom and was at its most influential in the first quarter of the 20th century. It was strongly associated with G. D. H. Cole and influenced by the ideas of William Morris.
