I think another major factor is that people imagine winning the lottery will solve all their problems because they feel like "money" is their single biggest problem and if that would go away, their life would work. In reality, they trade poor people problems for rich people problems and don't have rich people coping skills. They run out of money before developing them or they resist developing them because they are hesitant to be that cynical and jaded and they run out of money trying to prove to themselves that life does not boil down to "I've got dozens of friends and the fun never ends, that is as long as I'm buying."
