Davis & Moore argue that there need to be strata - or classes - of people with different power and pay, in order to ensure the best candidates get the most important jobs
Much of the research evidence suggests that the benefit system does not have the effect that Murray claims, and that many of the so-called underclass actually have conventional attitudes and want stable relationships and paid employment
Murray's analysis of the underclass is closely associated with New Right theories which also blame the benefits system for producing groups who are unable or unwilling to earn their own living
Townsend's preferred measure of poverty - individuals, families and groups fall into relative poverty when they lack the resources to obtain the types of diet, participate in activities and have the living conditions that are widely available in the society in which they live
1. Questionnaires issued to over 2,000 households and more than 6,000 individuals located in various geographical areas in the UK
2. Devised a deprivation index covering a large number of variables including diet, fuel, clothing, housing conditions, working conditions, health, education and social activities
3. Calculated a threshold for levels of income below which the amount of deprivation rapidly increased
Townsend believed more than 22% of the population to be living in poverty in 1968–69, this compared to just over 6% using the state standard and a little over 9% using relative income
Townsend's methods and conclusions have been criticised by those who argue that his index was inadequate and produced potentially misleading results, for example the absence of fresh meat and cooked meals might not be an indicator of poverty but of individual choice
Weber argued that collective action could result from a shared status situation (level of prestige or esteem) resulting from individuals' shared occupations, ethnicity, religion or lifestyles
