quote from the death of a salesman

"BIFF: Why? You’re making money, aren’t you?

HAPPY [moving about with energy, expressiveness]: All I can do now is wait for the merchandise manager to die. And suppose I get to be merchandise manager? He’s a good friend of mine, and he just built a terrific estate on Long Island. And he lived there about two months and sold it, and now he’s building another one. He can’t enjoy it once it’s finished. And I know that’s just what I’d do. I don’t know what the hell I’m workin’ for. Sometimes I sit in my apartment—all alone. And I think of the rent I’m paying. And it’s crazy. But then, it’s what I always wanted. My own apartment, a car, plenty of women, and still, goddamnit, I’m lonely." (Act 1)

Although Happy has accumulated a substantial amount of money and been surrounded by girl, it seems like it's not really what he wants. We can compare his situation to Gatsby's situation. Gatsby's rich in terms of the money and physical assets he had, however, he's missing a lot in terms of the spirit part, and the spirit part of his life, which would be being with daisy, is what he's after.
