Having experienced poverty makes one appreciate the small things in life and realise that the only way to survive or achieve a better life is to work hard. Those who have been born into wealth tend to take things for granted. they don't have to stress about how they will find enough money for food the next day, or afford to keep a roof over their head.
The same may go for entire countries. Some that have suffered a famine, recession or war may come back stronger whereas others that have always had power and prosperity may collapse and fail. Excellent questions posed in this piece, Nour.
