Murray: A group has developed below the main class system 'the underclass', which is defined not by its economic position, but by its attitudes & values. defined by their deviant & criminal behaviour & disregard for the law, and their failure to socialise their children adequately. This has increased bc of increasing welfare benefits, lead to a dependency culture, led to the decline of marriage, & single parent families, mens men no longer have to take responsibilty for supporting their families
