I get proxy forms from various companies on a fairly regular basis. They mostly signal elections for new Board members, and usually come with a recommendation by the company as to whom to vote for. I just throw them away. I figure that voting my tiny holdings wouldn't make any difference anyway.
I also have the sneaking suspicion that these elections are easily fixed.
The following scenario is all too easy to imagine: the CEO wants his guys on the Board of Directors, because he knows they will rubber stamp whatever he wants, including the bonus he wants to award himself. He goes to the accountants his firm has hired and tells them that if they want to continue to get business from him, to make sure his guy gets elected. What choice does that leave the accounting firm?
It makes no difference to them who's on the Board; but it makes a huge difference to them whether they get that company's business. They also know that no one will find out: when was the last time you ever heard of someone demanding a recount on a proxy vote?
Newsflash: people will lie if it's in their own best interest.
I'm not even sure similar shenanigans don't go on in Presidential elections.
