“-A landlord is a person who owns land, does not engage in labor himself, or does so only to a very small extent, and lives by exploiting the peasants. The collection of land rent is his main form of exploitation; in addition, he may lend money, hire labour or engage in industry or commerce. But his exaction of land rent from the peasants is his principle form of exploitation. The administration of communal land and the collection of rent from school land are included in the category of exploitation through land rent.
A bankrupt landlord shall still be classified as a landlord if he does not engage in labor but lives by swindling or robbing others or by receiving assistance from relatives or friends, and is better off than the average middle peasant.
Warlords, officials, local tyrants and evil gentry are political representatives and exceptionally ruthess members of the landlord class. Minor local tyrants and evil gentry are also very often to be found among the rich peasants.
Persons who assist landlords in collecting rent and managing property, who depend on landlord exploitation of the peasants as their main source of income and are better off than the average middle peasant shall be put in the same category as landlords.
Usurers are persons who rely on exploitation by usury as their main source of income, are better off than the average middle peasant, and shall be put in the same category as landlords.
-The rich peasant, as a rule owns land. But some rich peasants own only part of their land and rent the remainder. Others have no land of their own at all and rent all their land. The rich peasant generally has rather more and better instruments of production and more liquid capital than the average and engages in labor himself, but always relies on exploitation for part or even the major part of his income. His main form of exploitation is the hiring of labor (long-term laborers). In addition, he may let part of his land and practise exploitation through land rent, or may lend money or engage in industry and commerce. Most rich peasants also engage in the administration of communal land. A person who owns a fair amount of good land, farms some of it himself without hiring labor, but exploits other peasants by means of land rent, loan interest or in other ways shall be treated as a rich peasant. Rich peasants regularly practise exploitation and many derive most of their income from this source.
-Many middle peasants own land. Some own only part of their land and rent the rest. Others own no land of their own at all and rent all their land. All of them have a fair number of farm implaments. A middle peasant derives his income wholly or mainly from his own labor. As a rule he does not exploit others and in many cases he himself is exploited by others, having to pay a small amount in land rent and in interest on loans. But generally he does not sell his labor power. Some middle peasants (the well-to-do middle peasants) do practise exploitation to a small extent, but this is not their regular or their main source of income.
-Among the poor peasants some own part of their land and have a few odd farm implements, others own no land at all but only a few odd farm implements. As a rule poor peasants have to rent the land they work on and are subjected to exploitation, having to pay land rent and interests on loans and to hire themselves out to some extent.
In general, a middle peasant does not need to sell his labor power, while the poor peasant has to sell part of his labor power. This is the principle criterion for distinguishing between a middle and poor peasant.
-The worker (including the farm laborer) as a rule owns no land or farm implements, though some do own a very small amount of land and very few farm implements. Workers make their living wholly or mainly by selling their labor power.”- Mao Tse-Tung (Source: http://www.bannedthought.net/China/Individuals/MaoZedong/Books/SelectedWorksOfMao-V1.pdf)
