At what point will one say that he or she has had enough money?
For me when you own your house and the land where your house is built, that's when the time you can say you have enough money in this world.
I sincerely agree with you; the basic need of man include shelter, food, health and few others. Anybody that can afford those without much stress should be considered as having money.
Another reason I see a lot of people also want more money is to be able to help others who are in need and who may not be privileged to make ends meet. My greatest joy is putting a smile in someone else's face and I cannot do very well without money as majority of the world is going through financial stress at the moment.
So the quest for money is a continuous one and will only stop when money is no longer a factor in the equation of life.
