Quote #7
"I can't marry you and ruin both our lives." (2.1.411)
Rosalind doesn't want to marry Amory because she's certain that she'll make him miserable. The truth is that Amory isn't good/wealthy enough for her. Rosalind knows she'll never be happy unless she marries someone rich and respectable, and even though she loves Amory, she feels that love isn't enough.
Quote #8
"I'm sick of a system where the richest man gets the most beautiful girl if he wants her, where the artist without an income has to sell his talents to a button manufacturer." (2.5.206)
The fact is that Amory wants all that life doesn't have to offer. He wants to be appreciated (and paid) simply for being who he is and he wants a beautiful girl at his side. But he doesn't feel as though he should have to play the game to get these things. He doesn't want to work for some boring company to make his money, and he doesn't want beautiful girls to flock to men just because the men are rich.
Quote #9
Here was a new generation, shouting the old cries, learning the old creeds, through a revery of long days and nights; destined finally to go out into that dirty gray turmoil to follow love and pride. (2.5.245)
Amory looks around and sees a bunch of young people who are about to go through the exact same process he has. They're going to lose their youthful enthusiasm as soon as they realize how boring they'll have to become to live a comfortable adult life. They'll start with a lot of pride, but Amory is convinced they'll all get beaten down like him. There's a depressing thought.
