This shows how old money makes people used to it. It's not out of the ordinary and its a comfortable place to be. Tom isnt completely "happy" however, he feels he must also commit adultery to satisfy himself. That is, until Myrtle gets killed. Gatsby is new to money and he wants to show it off. This also makes people suspicious on how he got his money so fast. He too is not completely satisfied with his life. This is where Daisy comes in. She seems to make both sides happy in different ways. Tom loves Daisy but feels he needs Myrtle too and Gatsby wants Daisy all for himself. It seems that no matter which side you come from, you're always wanting more.
