There is a correlation but the direction of causation isn't always the direction you would think. Take the famous delayed gratification study where kids were given 2 treats if they didn't eat the 1 that was placed in front of them. More recent studies have indicated that eating the treat immediately may be a developed response to deprivation. And that wealthier kids were more likely to delay gratification--possibly because their experience taught them to believe the adult when they said there would be to 2 treats available later. According to the new results, the will power displayed in the delayed gratification tests was a result of wealth not a cause of wealth.
