What are the motifs in Black Boy by Richard Wright?

Poverty and hunger are interconnected and both are terrifying aspects of Richard’s life, especially during his younger years. He suffers from near starvation, and serious malnutrition. For many years he exits on mush for breakfast and a plate of greens for his second meal. Richard sometimes accompanies his mother to her job cooking for a white family. He watches as they eat lavish and bountiful amounts of food while he gets a few scraps.
