What is crooks dream? Why does he give up on his dream?

Crooks dream is to be a part of something, even if it's only a small part, but he doesn't believe the dream will ever come true.

"… If you … guys would want a hand to work for nothing—just his keep, why I’d come an’ lend a hand. I ain’t so crippled I can’t work like a son-of-a-bitch if I want to."

Crooks called, "Candy!"

"Huh?"

" ’Member what I said about hoein’ and doin’ odd jobs?"

"Yeah," said Candy. "I remember."

"Well, jus’ forget it," said Crooks. "I didn’ mean it. Jus’ foolin’. I wouldn’ want to go no place like that."

"Well, O.K., if you feel like that. Goodnight."

Crooks doesn't think any kind of dream is possible with white men. Crooks is too dejected. White men have shown him nothing but disdain so he doesn't see this dream as possible
