Lee and Young developed left realism in the early 1980s as a response to rising crime rates and the need for realistic solutions to crime issues
They were influenced by various theories, including Marx's theories of structural inequality and interactionist theories focusing on the role of the state, media, and police in labeling individuals
Left realism aimed to provide an alternative to right realist policies dominating criminal justice policies of new right governments
Crime is not caused by a single factor but a combination of factors working together
Jock Young argued that the causes of crime include structural inequality, informal and formal social control mechanisms, and individual agency
Lee and Young identified three main factors influencing the rising level of crime:
Relative deprivation
Growth of subcultural responses to society's unequal structure
Marginalization
Relative deprivation is when people feel they lack the same economic resources as others in society, leading to criminal behavior
Subcultures are responses to societal pressures and economic success, providing relief from relative deprivation and status within the group
Marginalization occurs when groups have minimal representation in society, leading to frustration and anti-social behavior as a form of protest
Lee and Young's work built on various theorists' ideas and influenced criminal justice policies in the late 1990s under New Labour
Critics suggest their work is theoretical and not research-based, pointing to the decline of recorded crime in the era of global capitalism
However, unreported crimes and the manipulation of recorded crime data for ideological and political purposes are factors to consider
