Interestingly, there were 3 justices that were around for both the flag burning case and Citizen's United (money-is-speech case): Scalia, Kennedy, and Stevens.
Scalia and Kennedy were in the majority (broad speech rights) in both cases and Stevens was in the minority (narrower speech rights) in both cases.
So, I guess (loosely speaking) if fire is speech, then money is speech too.
