Final answer:
Lavell (2011) suggests that poverty-class clients may be suspicious of people in authority and tend to focus on living in the present moment.
Step-by-step explanation:
A potential characteristic of poverty-class clients in practice according to Lavell (2011) include a suspicion of people in authority and a tendency to live in the here and now. These characteristics highlight the defensive posture that individuals in poverty might adopt due to past experiences with institutions and authority figures, as well as the immediate pressures of their daily lives that focus their attention and resources on present concerns rather than future planning.
