The classic historical study of proletarianization is
E.P. Thompson's
The Making of the English Working Class (1963), in which the author portrays the meanings, struggles and conditions of an emerging proletariat. Many
intellectuals have described proletarianization in
advanced capitalism as "the extension of the logic of factory labor to a large sector of services and intellectual professions." In most countries, entitlement to unemployment benefits is conditional on actively looking for work, and that means people, assuming they are not sick, are
compelled to seek employment either as a salaried worker or as a self-employed worker. Geographically and historically, the process of proletarianization is closely associated with
urbanization because it has often involved the migration of people from rural areas where they engaged in subsistence farming, family farming and sharecropping to the cities and towns, in search of waged work and income in an office or factory (see
rural flight). ==A cultural explanation==
