You are talking from a position of total ignorance and painting everyone with the same brush, some would fall into your category but tbh i have never witnessed a "feral" person tear up £50 notes in front of a homeless man or stick his cock in a dead pigs mouth or allow dangerous cladding to fitted to a tower block in which 72 die.
These people may not live off benefits but they are also very horrible individuals.
I came from what you would describe as an underclass family, single parent, DB always in trouble with the Police/School/anyone lived off social security.
Up shot was this "underclass family" produced a Telecoms engineer, a teacher and an civil engineer, Mum re trained with help from a charity to become a nurse SEN.
