Throwing this out.

Cut tax breaks for advertising. That would probably make them more efficient, but it would certainly not help Palin's crusade.

As long as I am tossing out nuggets, how about:
One stockholder: One vote!
If you want more than your share? Buy it. *
Now that is tergiversation.(Changing one's opinion.)
Actually a ludicrous leap, but which demonstrated tendencies to let the market fix it. But maybe a tax break for investors up to a limit, per company, to distribute the vote. If you want more than one vote, buy shares in more than one company. Maybe corporations need a new hierarchy **. They are not in the constitution, but the word "welfare" is.(Pre-amble) There are three branches of the government, and the separation of press and business is as important as church and state, though not directly a corollary or balanced. (First Amendment) The point is (well) there is a lot of water under the bridge or rubric of precedence, which may be undermining our fundamentals, AKA "the people".

* update: The irony or unsatire slipped in here. I was going to clarify the Buy It crack, but I had already explained the ludicrous leap: Tax incentives or regulations which would revalue the voice of people and money.
** corporations are not in the constitution, they are and have been constituted by government and people. With all the irony of the moral hypocrisy over the death penaly and cloning, just how have we allowed the creation of such Leviathans.
