Should, could, would - are all nice and all.
Convincing democratically-elected representatives to stop receiving money, money they use to buy votes, is a futile fight. Even if you do, many will just be corrupt and still accept money or other kinds of payment. IMHO, I'm starting to think that this system is really good - at least you have the means to find out who paid what and to whom.
Killing Hollywood, or at least doing something to make them think twice the next time, now that's doable.
