Over the past five years, [Perkins] has accumulated a mass of evidence about the personalities of welfare claimants and concluded that individuals with aggressive, rule-breaking and anti-social tendencies — what he calls the ‘employment–resistant personality profile’ — are over-represented among benefit recipients. He also found that their children are likely to share those traits, which helps explain why poverty has a tendency to be passed down from one generation to the next.
