I think I mostly understand this, but if someone could flesh out por vs. para in this sentence I'd appreciate it. I know "Por que" is why, and I guess that is different than "for what," but I don't quite see how.
Yes! I just looked this up. When asking questions, "¿Por qué?" means "Why?" (for what reason) while "¿Para qué?" means "Why?" (for what purpose). The wording here implies the speaker is seeking out a purpose for the money.
