People are just greedy, greedy for money and they are all looking for a way to get rich quick.
Some people believe gambling is the way to go, just because they won 1 time big they will keep trying to win again and again, they think that they can get rich by doing so. While meanwhile they keep losing all that money and start creating their debt.
Greed is good if it's for something that isn't harmful for others like greed for success, greed for achievement but greed for money is very harmful, not only for others but for the person himself.
