Some poor people believe in themselves and have a level of determination as well as a healthy dose of expectations and goals that they would personally like to meet. These types of people know that the poor life they experience(d) is not what they want and aim higher. If they can get resources (money, education, experiences, etc.) and opportunities to line up, watch out, their star will shine brightly!
Some affluent people may take for granted and may simply not know anything outside of tremendously aesthetically pleasing single, double and triple guard gated communities because others are doing life's heavy lifting for them. These types may or may not have a clue as to what they want and may lack the determination to get there because things could already be very comfy for them in various ways, possibly due to the efforts of others. Some affluent types literally may not know how difficult life could be and may take it for granted whereas poor people have a much better idea and may be or become highly motivated to climb upwards.
