People need money to live, and enough to buy the basic goods one needs to survive, but everybody wants more money. More money means an easier life. The more money one has, the more money one wants, as is shown in the story, "The Rocking Horse Winner" by D. H. Lawrence.
At the beginning of this story the family did not have enough money to support their opulent lifestyle. Mr. Lawrence illustrates their situation like this: "Although they lived in style they felt always an anxiety in the house. There was never enough money." (p. 159) The family scrambles to pay the bills at the end of the month.
