Other forms of market socialism are based on classical economics, such as those advocated by Thomas Hodgskin, who viewed interest accumulation, rent and profit as deductions from exchange-value, so that eliminating the capitalist element from the economy would lead to a free market and socialism. The term market socialism has also been applied to planned economic systems that try to organize themselves partially along market-lines while retaining centralized state ownership of capital. Examples of market socialism include economic democracy, the Lange model, liberal socialism, market-oriented left-libertarianism, mutualism the New Economic Mechanism and Ricardian socialism. Other types of market socialist systems such as mutualism are related to the political philosophy of libertarian socialism. A socialist market economy refers to the economic systems adopted by the People's Republic of China and the Socialist Republic of Vietnam. Although there is dispute as to whether or not these models actually constitute state capitalism, the decisive means of production remain under state-ownership. State enterprises are organized into corporations (corporatization) and operate like private capitalist enterprises. A substantial private sector exists alongside the state sector of the economy, but it plays a secondary role usually relegated to the service sector and production of consumer goods. Examples of socialist market economies include the socialist market economy with Chinese characteristics and the socialist-oriented market economy. Utopian socialism is a term used to define the first currents of modern socialist thought as exemplified by the work of Henri de Saint-Simon, Charles Fourier and Robert Owen, which inspired Karl Marx and other early socialists. However, visions of imaginary ideal societies, which competed with revolutionary social democratic movements, were viewed as not being grounded in the material conditions of society and as "reactionary". Although it is technically possible for any set of ideas or any person living at any time in history to be a utopian socialist, the term is most often applied to those socialists who lived in the first quarter of the 19th century who were ascribed the label "utopian" by later socialists as a negative term, in order to imply naivete and dismiss their ideas as fanciful or unrealistic. Forms of socialism which existed in traditional societies, including pre-Marxist communism are referred to as primitive communism by Marxists. As a socialist-positivist politic view created by Auguste Comte, sociocracy is based on Saint-Simon's aristocratic, utopian socialism heritage, prioritizing social justice and a central government with direct democracy without parliament. Religious sects whose members live communally, such as the Hutterites, for example, are not usually called "utopian socialists", although their way of living is a prime example.
