Относительная депривация: измерение бедности и социальной исключенности

Measure of poverty and social exclusion
Relative deprivation is the lack of resources to sustain the diet, lifestyle, activities and amenities that an individual or group are accustomed to or that are widely encouraged or approved in the society to which they belong. Measuring relative deprivation allows an objective comparison between the situation of the individual or group compared to the rest of society. Relative deprivation may also emphasise the individual experience of discontent when being deprived of something to which one believes oneself to be entitled, however emphasizing the perspective of the individual makes objective measurement problematic. It is a term used in social sciences to describe feelings or measures of economic, political, or social deprivation that are relative rather than absolute. The term is inextricably linked to the similar terms poverty and social exclusion. The concept of relative deprivation has important consequences for both behaviour and attitudes, including feelings of stress, political attitudes, and participation in collective action. It is relevant to researchers studying multiple fields in social sciences. Social scientists, particularly political scientists and sociologists, have cited relative deprivation, especially temporal relative deprivation, as a potential cause of social movements and deviance, leading in extreme situations to political violence such as rioting, terrorism, civil wars and other instances of social deviance such as crime. For example, some scholars of social movements explain their rise by citing grievances of people who feel deprived of what they perceive as values to which they are entitled. Similarly, individuals engage in deviant behaviours when their means do not match their goals. According to a June 2015 report by the IMF, the defining challenge of our time is widening income inequality. In advanced economies, the gap between the rich and poor is at its highest level in decades. Inequality trends have been more mixed in emerging markets and developing countries (EMDCs), with some countries experiencing declining inequality, but pervasive inequities in access to education, health care, and finance remain.

Feelings of deprivation are relative, as they come from a comparison to social norms that are not absolute and usually differ from time and place. This differentiates relative deprivation from objective deprivation (also known as absolute deprivation or absolute poverty) a condition that applies to all underprivileged people. This leads to an important conclusion: while the objective deprivation (poverty) in the world may change over time, relative deprivation will not, as long as social inequality persists and some humans are better off than others. Consider the following examples: in 1905 cars were a luxury, hence an individual unable to afford one would not feel or be viewed as deprived. In 2010, when cars are common in most societies, an individual unable to afford one is much more likely to feel deprived. In another example, mobile phones are common today, and many people may feel that they deserve to have one. Fifty years ago, when there were no mobile phones, such a sentiment would not exist. Relative deprivation may be temporal; that is, it can be experienced by people that experience expansion of rights or wealth, followed by stagnation or reversal of those gains. Such phenomena are also known as unfulfilled rising expectations. In an example from the realm, the lack of the right to vote is more likely to be felt as a deprivation by people who had it once than by the people who never had the opportunity to vote.

Some scientists, for instance John Kenneth Galbraith, have argued that relative differences in economic wealth are more important than absolute deprivation, and that it is more significant in determining human quality of life. This debate has important consequences for social policy, particularly on whether poverty can be eliminated simply by raising total wealth or whether egalitarian measures are also needed. A specific form of relative deprivation is relative poverty. A measure of relative poverty defines poverty as being below some relative poverty line, such as households who earn less than 20% of the median income.

Critique of this theory has pointed out that this theory fails to explain why some people who feel discontent fail to take action and join social movements. Counter arguments include that some people are prone to conflict avoidance, are short term oriented, and that imminent life difficulties may arise since there is no guarantee that life improvement will result from social action.
