Marty: "Well, hey, Doc, what's the harm in bringing back a little info on the future? Maybe we could place a couple of bets."
Doc: "Marty! I didn't invent the time machine for financial gain. The intent here is to gain a clearer perception of humanity: where we've been, where we're going, the pitfalls, the possibilities, the perils and the promise. Perhaps even an answer to that universal question: why?"
Marty: "Hey, Doc, I'm all for that. But what's wrong with making a few bucks on the side?"
