Analyzing Dialogue

"I guess you'll never become a samurai now, huh, Manjiro-chan?"
"Why not?" Manjiro asked.
"Even if we should get home, you know very well you can't be. You weren't born into a samurai family. You were born a fisherman's son and you will be a fisherman, and any sons you have, they also will be fishermen. That is the way it is; that is the way it has always been; that is the way it will always be."
